  • Effect of Low-Temperature Plasma Treatment on Surface Modification of
           Polycaprolactone Pellets and Thermal Properties of Extruded Filaments
    • Abstract: Abstract Polycaprolactone (PCL) polymer has been surface modified using oxygen low-temperature plasma and melt extruded into single filaments. Oxygen plasma was generated using a radiofrequency source with power of 150 W. The PCL polymer samples were treated with plasma for various durations of 5 min, 10 min, and 20 min. Water contact angle measurements were carried out to assess the wettability, revealing that the treatments reduced the contact angle by up to 11°. Changes in the chemical bonding and surface compositions were characterized by using x-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy, revealing a high concentration of oxygen functionalities on the surface. Crystallinity changes were studied by using x-ray diffraction analysis. The surface morphology of the polymer was investigated using field-emission scanning electron microscopy. The thermal degradation and melting behavior was studied using thermogravimetric analysis and differential scanning calorimetry, respectively.

  • Non-isothermal Phase-Field Modeling of
           Heat–Melt–Microstructure-Coupled Processes During Powder Bed Fusion
    • Abstract: Abstract Modeling and simulation of powder bed fusion (PBF) remain a great challenge due to the sophisticated and interactive nature of underlying physics. A unified scenario considering interactions among the heat transfer, melt flow dynamics and microstructure evolution (noted as “heat–melt–microstructure-coupled processes”) is therefore essential for a thermodynamically consistent description and thus reliable microstructure prediction. In contrast to the state of the art, where either individual aspects are considered or the thermal history is taken as input from separate numerical scheme, we propose in this work a unified non-isothermal phase-field model for the heat–melt–microstructure-coupled processes during PBF. Simulations on a stainless steel 316L powder bed demonstrate that the model can reproduce well-observed features, but also help to discover new in-process phenomena and reveal the mechanism of the defect formation. Based on massive simulation results, we also present the densification map with respect to beam power and scan speed, and have classified the regions of the parameter combination by the distinct resultant morphology.

  • Friction Stir Lap Welding of Mg/Ti Dissimilar Alloys Using a Slight
           Penetration Depth
    • Abstract: Abstract Friction stir lap welding was applied to join AZ31B Mg alloy and Ti-6Al-4V alloy using a slight penetration depth. The microstructure and tensile properties of the joints formed using different rotating speeds were investigated. The results showed that a dispersion layer comprising Ti fragments with size of less than 15 μm formed in the stir zone near the lap interface. A wave-like pattern formed on the surface of the bottom Ti alloy, leading to micromechanical interlocking. A 2.1-μm-thick Al enrichment layer formed at the lap interface when using the rotating speed of 1400 rpm, resulting in metallurgical bonding. The joints fractured at the lap interface, and the local region of the fracture surface on the Ti alloy side was covered with Mg alloy. The tensile shear strength of the joints increased with increase of the rotating speed, and the maximum tensile shear load reached 9765 N for the joint prepared at 1400 rpm.

  • The Effect of Oxygen Addition on Microstructure and Mechanical Properties
           of Various Beta-Titanium Alloys
    • Abstract: Abstract Simultaneously achieving high strength and low Young’s modulus is essential for implant materials due to the “stress-shielding effect”. In this work, the mechanical properties and microstructure of various beta-titanium alloys based on the Ti-Nb system with additions of Zr, Ta and Sn have been studied. Those alloys were prepared via the arc melting process. Thermo-mechanical processing (i.e., hot forging, solution treatment and cold swaging) has been performed. The alloys exhibited low Young’s modulus around 50 GPa (43 GPa was the lowest measured value) and tensile strength around 800 MPa. The tensile strength was increased via aging treatment (450°C/8 h) to 985 MPa while the modulus increased to 75 GPa. On the other hand the addition of 0.4 wt.% of oxygen seems to be more beneficial as the tensile strength reached values as high as 1225 MPa and simultaneously maintained low Young’s modulus (~ 62 GPa) and sufficient elongation (~ 8%).

  • Shear Punch Testing of Neutron-Irradiated HT-9 and 14YWT
    • Abstract: Abstract Shear punch mechanical testing was performed on neutron-irradiated HT-9 and 14YWT alloys, comparing the traditional ferritic/martensitic steel with the advanced oxide dispersion strengthened nanostructured ferritic alloy. The samples were irradiated at various temperatures between 380°C and 520°C. In HT-9, on increasing the irradiation temperature, the 1% offset shear stress and maximum shear stress decreased. The advanced 14YWT alloy was less sensitive to irradiation temperature with respect to irradiation hardening. However, it still exhibited irradiation hardening at each temperature.

  • Comparative Study of the Planar Uniformity of the Mechanical Properties of
           the AA1050 Strips Processed by Conventional and Cross Accumulative
           Roll-Bonding Techniques
    • Abstract: Abstract In this research, a modified method of the conventional accumulative roll-bonding (ARB) process, named cross accumulative roll-bonding (CARB), was applied on an AA1050 strip for up to 13 cycles. The planar uniformity of the mechanical properties in the products of ARB and CARB processes has not been investigated yet. This article aims to compare the planar inhomogeneity of the tensile properties in different directions of the rolling plane of the ARB- and CARB-processed specimens. For this purpose, uniaxial tensile tests were performed in the rolling, transverse, and diagonal directions of the products. Furthermore, Vickers microhardness was used to investigate the hardness distribution throughout the thickness of specimens. The results revealed that the CARB process exhibited higher tensile strength, elongation, and hardness with more homogeneous distribution of the hardness and particularly better planar uniformity of the tensile properties compared with the conventional ARB process.

  • Extraordinary Strengthening of Magnesium by Solid-State Diffusion of
           Copper in Mg-0.5Cu Alloy
    • Abstract: Abstract A powder-processed hot-extruded high-performance Mg-0.5 wt.% Cu alloy has been developed by solid-state diffusion of elemental copper into commercially pure magnesium powder. Copper, in nanoparticle form, was blended to form a dry-coat layer on micrometer-size magnesium particles, which subsequently homogeneously diffused, forming a single-phase solid solution during the sintering process. Copper as a solute atom did not act as a grain refiner. Investigation of the mechanical properties revealed that the strength properties of commercially pure magnesium were significantly improved (macrohardness by 32.5%, microhardness by 42.7%, tensile yield strength by 114%, tensile strength by 69%, compressive yield strength by 46%, and compressive strength by 48%) due to the dissolution of copper as solute atoms. The ductility of the magnesium suffered marginal loss despite the fracture mode being ductile, which was due to decohesion at the magnesium interparticle boundaries induced by the relatively higher copper concentration.

  • Hot Deformation Behavior and Microstructure Mechanisms of As-Cast 2219 Al
    • Abstract: Abstract The hot deformation behavior of ultralarge 2219 Al alloy has been investigated by isothermal deformation tests. The microstructure was characterized by transmission electron microscopy, scanning electron microscopy, and electron backscattered diffraction analysis. The results indicated that the true stress increased rapidly during the initial stage of deformation, then remained stable after reaching the peak stress. The peak stress increased with decreasing temperature and increasing strain rate. It was found that the main restoration mechanisms were dynamic recovery and partial continuous dynamic recrystallization (CDRX). The submicron θ or θ′ particles had a pinning effect on the dislocation motion and grain boundary sliding, and suppressed the CDRX process. In addition, the irregular millimeter- or micron-sized θ particles were broken up during deformation, effectively relaxing the stress concentration and inducing the DRX process.

  • Development of an Al-Mn-Si-Based Alloy with an Improved
           Quasicrystalline-Forming Ability
    • Abstract: Abstract This investigation deals with the influence of calcium, strontium and zinc on the formation of primary, metastable quasicrystals in Al-Mn-Si alloys as these can enhance the mechanical properties of alloys. The synthesized alloys were cast into a copper mould. The castings were characterized using standard tools for studying microstructure. The Al-Mn-Si-Zn-Ca-Sr alloy contained more of the primary icosahedral quasicrystalline (iQc) phase and less of the approximant α-Al-Mn-Si phase than the Al-Mn-Si alloy. The higher volume fraction of the primary iQc phase in the Al-Mn-Si-Zn-Ca-Sr alloy is explained by the reduction of the critical radius size for nucleation and by an increase in the number of nucleation sites for the iQc phase. Increased number of nucleation sites and higher volume fraction of the primary iQc are both related to a reduction of the surface tension for the Al-based melt caused by the presence of calcium and strontium. These two elements do not become incorporated into the iQc phase but have a large effect on the course of the solidification of the investigated alloys and their constitution at room temperature.

  • Achieving High Ductility in Hot-Rolled Mg-xZn-0.2Ca-0.2Ce Sheet by Zn
    • Abstract: Abstract The mechanical behavior of hot-rolled Mg-xZn-0.2Ca-0.2Ce (x = 0.5 wt.%, 1.0 wt.%, 1.5 wt.%, 2.0 wt.%) was studied by the uniaxial tension test. Meanwhile, the microstructure and texture were analyzed using an optical microscope, x-ray diffraction and scanning electron microscope. The sheets exhibited a bimodal basal texture along the transverse direction (TD). Zn addition led to an increase of the TD tilted texture component and a reduction of the rolling direction tilted texture component. However, the yield strengths were not always increasing when the amount of Zn increased, which was related to the solid solution softening and unique texture distribution. The best ductility and formability were obtained in Mg-1.5Zn-0.2Ca-0.2Ce alloy with fracture elongation of ~ 42.1% and Erichsen value of 7.7 mm. The enhanced plasticity and formability were owing to the modified texture, non-basal slips and enhanced grain boundary cohesion.

  • Effect of Heating Mode on Thermal Stability of Nanocrystalline
    • Abstract: Abstract This study reports the effect of heating mode on the thermal stability of nanocrystalline hydroxyapatite (HA) by comparing conventional electric resistance heating and microwave heating of HA to 1100°C under the same experimental conditions. It was found that, compared with conventional heating, microwave heating of HA resulted in less hydroxyapatite decomposition and a higher Ca/P molar ratio of the product (1.42 versus 1.37) in association with a smaller lattice contraction of the phase probably caused by the selective thermal effect of microwave radiation. It also produced smaller grains (56.54 nm versus 64.32 nm) along with a higher specific surface area and larger total pore volume, featured by the differences of 36.80% and 79.29%, respectively. Moreover, it led to more homogeneous pore distribution. These physicochemical features are expected to contribute to superior mechanical and biologic properties of the final product.

  • Unified Effect of Dispersed Xe on the Thermal Conductivity of UO 2
           Predicted by Three Interatomic Potentials
    • Abstract: Abstract Thermal conductivity is a critical fuel performance property of uranium dioxide (UO2)-based nuclear fuels. Numerous studies have shown that xenon (Xe) fission gas plays a major role in fuel thermal conductivity degradation. It has also been shown that dispersed Xe atoms can cause a stronger phonon-scattering effect than their clustered form. In this work, molecular dynamics simulations are conducted to study the dispersed Xe-induced thermal conductivity reduction using three different interatomic potentials. It is found that although these potentials result in significant discrepancies in the absolute thermal conductivity values, the normalized values are very similar at a wide range of temperatures and Xe concentrations. By integrating this unified effect into the experimentally measured thermal conductivities, a new analytical model is developed to predict the realistic thermal conductivities of UO2 at different dispersed Xe concentrations and temperatures. Using this new model, the critical Xe concentration that offsets the grain boundary Kapitza resistance effect in a high burnup structure is revisited.

  • Influence of the Nb Content on the Microstructure and Phase Transformation
           Properties of NiTiNb Shape Memory Alloys
    • Abstract: Abstract NiTi shape memory alloys (SMAs), as smart materials, are broadly used in medical implants and appliances despite the presence of toxic Ni. In this study, NiTiNb alloys were produced using the substitution of biocompatible Nb instead of Ni. The arc-melting method was utilized to make five SMA samples comprising Ni(29−x)Ti50Nb(21+x) (x = 0, 1, 2, 3, and 4); then, the phase transformation temperatures, microstructures, crystal structures, and chemical compositions were investigated by DSC, optical microscopy, XRD, and EDX measurements, respectively. The DSC results showed that the samples had a wide hysteresis with the B19′↔B2 phase transformation and martensite start temperatures below room temperature, which makes them suitable for superelastic implants. The presence of dissolved Nb in the matrix of the alloys was the main reason for the widening of temperature hysteresis. When the XRD and SEM results were examined, the β-rich, B2, B19′, and Ti2Ni phases were observed in all samples. Additionally, the main constituent in the dendritic microstructures was Nb.
