  • INVESTIGATION OF THE EFFECT OF NITROCARBURIZING TREATMENT ON TRIBOLOGICAL
           PROPERTIES OF AISI 1045 MEDIUM CARBON STEEL

    • Authors: Elhadj GHELLOUDJ
      Pages: 5 - 9
      Abstract: In this paper, the effect of nitrocarburizing treatment on tribological properties of AISI 1045 steel was investigated. This medium carbon steel was used in automotive industry, especially in the manufacture of machine components due to the good mechanical properties and lower cost. Characterization of the surface layer of treated samples was made by optical microscopy (OM), Vickers microhardness test, scanning electron microscope (SEM), and pin-on-disk wear machine. Experimental results showed that the surface layers formed through nitrocarburizing processing at 580 °C (compound layer and diffusion zone) increased the microhardness. It was found also that the nitriding treatment reduced the friction coefficient and improved the wear resistance, where the specific wear rate were decreased to 1/9 was noticed after 10 hours of nitriding time.

  • Performance Evaluation of Coconut Oil Based Cutting Fluid with
           Biodegradable Additives on Cylindrical Turning of AISI 1040 Carbon Steel

    • Authors: Segun Adedayo, Bright Omoshola , Peter Omoniyi
      Pages: 10 - 13
      Abstract: This article analyzed the effect of coconut oil-based cutting fluid with emulsion properties of 5%. The cutting fluid was evaluated by comparing it with conventional cutting fluid (Petroleum Based). Machining temperature at the tool-workpiece interface was measured during straight turning operation on CNC machine at various cutting speeds, depths of cut, and fixed feed rate of 7.5 mm/min for 15 minutes. The Response Surface Methodology (RSM) was also used to determine the machining parameters' effect on each cutting fluid's temperature at the tool-workpiece interface. It was observed that the developed coconut cutting fluid outperformed the other cutting fluids as a coolant at all experimented speeds, with a maximum temperature of 63.5 °C at the working zone as against 90.6 °C observed for conventional cutting fluid and 163.8 °C for dry turning. The viscosity values obtained from the developed cutting fluid between 40 °C and 100 °C show the tendency of the developed cutting fluid to maintain its lubricity at a higher temperature. Depth of cut was also observed to have a significant effect on the temperature at the tool-workpiece interface.

      Abstract: Titanium tends to form nitrides and carbides. The plasma nitrocarburizing technique can generate these nitride and carbide compounds on the material's surface. The objective of this research is to use a plasma nitrocarburizing process to increase the hardness and corrosion resistance of commercially pure titanium. The generation of a thin layer with an average thickness of 1.88 μm was discovered using a Scanning Electron Microscope. The X-Ray Diffraction technique identifies this thin layer made of TiN and TiC compounds. The untreated commercially pure titanium hardness was 105.75 VHN, and the plasma nitrocarburized commercially pure titanium hardness was 312.68 VHN, according to the Vickers micro tester. After plasma nitrocarburizing, the corrosion rate of untreated commercially pure titanium decreased from 0.0061 mmpy to 0.00077 mmpy. The plasma nitrocarburizing process resulted in a 196 percent increase in hardness and an 87 percent reduction in corrosion rate.

  • METALLURGICAL AND MECHANICAL INVESTIGATION OF TIG ARC WELDMENTS FOR API
           32″ GAS PIPE

    • Authors: Taher El-Bitar, Maha El-Meligy, Mohammed Gamil
      Pages: 19 - 24
      Abstract: API steel gas pipe of 32" diameter and 15.9 mm thickness was investigated to characterize the steel grade and assess weldability for fourteen-consecutive passes of TIG arc welding technology. The parent Metal (PM) contains 0.02% C in addition to 0.02% Nb. A steel electrode for TIG process was used containing 5.6% Cr and 0.56% Mo. Standard V-groove was mechanically prepared to suite butt welding. The microstructure of the PM was containing mainly fine acicular ferrite satisfying the essential requirements of API specifications for grade X60. The weld metal (WM) was containing very fine acicular ferrite and showing the maximum hardiness values. Heat affected zone (HAZ) structure still contains acicular ferrite but it became coarse, possessing lower hardness than that of WM. HAZ does not exceed 2-2.5 mm adjacent to the welded V-groove. The fractured tensile welded specimens were necked and failed at the HAZ. The impact transition temperature (ITT) was detected as -35 oC. However, the mechanical properties of the WM did not negatively affected by the welding process and still fair satisfying the requirements of API X60.

  • PHYSICO-MECHANICAL PROPERTIES ANND MICROSTRUCTURE RESPONSES OF HYBRID
           REINFORCED Al6063 COMPOSITES TO PKSA/SiC INCLUSION

    • Authors: Peter Ikubanni, Makanjuola Oki, Adekunle Adeleke, Peter Omoniyi, Emmanuel Ajisegiri, Esther Akinlabi
      Pages: 25 - 32
      Abstract: The study examined the microstructure and mechanical properties of Al-Mg-Si alloy reinforced with palm kernel shell ash (PKSA) and silicon carbide (SiC). The alloy matrix was reinforced with SiC (2 - 8 wt.%) and PKSA (2 wt.%). The double stir-casting method was used to prepare the hybrid composite. The mechanical properties of the produced samples were evaluated based on ASTM standards.  Identification of phases present in the composite was done using a PANalytical Empyrean diffractometer, while the microstructural characterization was examined using a scanning electron machine with electron dispersive spectrometer attachment. The density values increase as the SiC contents in the composites increase. As the reinforcement particulates increase, the mechanical properties of the reinforced composite improved with hardness value (73 – 85.5 BHN); yield strength (81 – 102 MPa); and ultimate tensile strength (123 – 133 MPa) compared with the matrix alloy of 73 BHN, 79 MPa, and 116 MPa, respectively. However, the percentage elongation and the fracture toughness of the reinforced samples reduced to 34.2 and 40.11%, respectively. The phases identified in the composites were Al, SiO2, Fe3Si, MgO, and SiC.  The synthesized hybrid composites would be applicable as building materials such as aluminium frames and roofing sheets.

  • THE EFFECT OF ULTRA-FINE ALLOYING ELEMENTS ON THE PHASE COMPOSITION,
           MICROSTRUCTURE, HIGH-TEMPERATURE STRENGTH AND FRACTURE TOUGHNESS OF
           Ti–Si–X AND Ti–Cr–X COMPOSITES

    • Authors: Volodymyr Kulyk, Bogdan Vasyliv , Zoia Duriagina, Pavlo Lyutyy, Valentyna Vavrukh, Taras Kovbasiuk, Volodymyr Vira, Myroslav Holovchuk, Tetiana Loskutova
      Pages: 33 - 42
      Abstract: Advanced Ti-based composites are promising for applications in components of modern aircraft and rocket engines as well as other power equipment owing to their high strength-to-weight ratio and fracture toughness in a temperature range of 20 °C to 650 °C. However, there is a need to increase their operating temperature range up to 700−800 °C. In this work, mechanical behavior of Ti–Si–X composites (X=Al and/or Zr, Sn, C) has been studied. For comparison, mechanical behavior of Ti–Cr–X composite (X=Al and/or C) has been studied. As-cast and thermo-mechanically deformed series of beam specimens were examined. Strength tests of specimens were performed under three-point bending in a temperature range of 20 °C to 1000 °C. Single-edge notch beam (SENB) tests under three-point bending of specimen series were carried out in a temperature range of 20 °C to 900 °C for estimating fracture toughness of materials. Based on the constructed dependences of fracture toughness and strength on testing temperature for the specimen series as well as the microstructure and failure micromechanism analyses, the role of ultra-fine alloying elements in achieving good high-temperature strength and fracture toughness of the studied composites was substantiated.

      Abstract: Graduate students of technical universities have practical difficulties with learning and successful instructional implementation of the fundamentals of engineering didactics. The paper is focused on the formulation of a thought-provoking curriculum with computational assignments for the course of “Technical University Pedagogic and Methodological Foundations of Engineering Education” (TUPMFEE) for graduate and Ph.D. students. The paper uses computational modelling of behavioral processes in socio-educational systems. The TUPMFEE-curriculum teaches future engineers to apply computational techniques to modeling of socio-technical phenomena. The author-formulated and a computer modeling-supported metaphor for the psycho-educational effects of high social pressure impact on student learning dynamics was allegorically visualized using mechanical rolling stress distribution for the nonlinear social process of student knowledge acquisition during instructor-enhanced education with description of some successive forgetting of the previously acquired instructional material upon the studied course completion. The author-proposed TUPMFEE-course successfully triggers graduate students’ interest in both social, mechanical and computer sciences.
