• Physicomechanical Properties of Compositions Based on Butadiene–Nitrile
Rubbers after Long-Term Exposure to a Drilling Fluid

Abstract: The influence of a drilling fluid on the physicomechanical properties of commercial rubbers of two types (RTD-1, RTD-2), which are used as stator coatings for downhole drilling motors, is studied. Prolonged (60 days) contact with a drilling fluid at 25°C is found to increase the stiffness and the coefficient of mechanic loss of rubber. The stability of the properties of RTD-1 rubber during operation in contact with a drilling fluid is shown to be higher than that of RTD-2 rubber. At 80°C, the elastic–hysteresis properties of the rubbers of both types have deteriorated by 30–50%.

• Effect of the Chemical Composition and Structure of EP682-Sh and R6M5
High-Speed Steels on Their Hardness and Impact Toughness

Abstract: The hardness and impact toughness of high-speed steels EP682-Sh (R12FZK10M3-Sh) and R6M5 are studied, and methods for increasing their hardness are proposed. The optimum ratio of the carbon to vanadium content (C/V = 0.42) is determined; at this ratio, the hardness of the EP682-Sh steel of the modified composition after tempering at 520°C for 1 h performed six times is 71–72 HRC. After radial-shear rolling, high-speed steel is shown to be a precipitation-hardened composite material with uniformly distributed carbide particles, which increases the impact toughness and decreases the risk of cracking in rolling.

• Spall Fracture of High-Strength Steel during Quasi-Static Tension

Abstract: The fact that standard specimens made of high-strength bearing steel undergo spall fracture during quasi-static tension is experimentally proved. The uniqueness of this fracture consists in the fact that it proceeds due to the elastic energy of the specimen, in contrast to the classical spallation during high-speed collision or a high-energy pulsed external action. High-speed video filming is used to demonstrate that the mode I fracture of a specimen and its subsequent spall fracture are spaced in time.

• Effect the Thermal Cycle of Welding and Thermal Cycling Treatment on the
Properties and Fracture of 08Kh18G8N2T Steel

Abstract: The impact toughness and phase-structural transformations in 08Kh18G8N2T steel are studied after a thermal action, which simulates the heating of the near-weld zone during electroslag welding, and subsequent thermal cycling treatment under various conditions. An increase in the impact toughness from 0.25 to 1.2 MJ/m2 is detected after thermal cycling in the temperature range 700–900°C at a rate of 1°C/s, which is associated with the redistribution of alloying elements between phases, structure fragmentation, and the morphology of excess phases.

Aluminum Alloy by an Ice Granule Flux

Abstract: The response of solids (TOSP-1 polymethylmethacrylate, D1 aluminum alloy) to multiple collisions with 1-mm ice granules with an average velocity of about 100 m/s is experimentally studied at low climatic temperatures (–40°C). When ice granules collide with a target, 100-μm fragmentation particles are found to form and cause the destruction of the target surface.

• Effect of Heat Treatment on the Structure and Mechanical Properties of the
Solid-Phase VT6 Alloy Welded Joint with an Ultrafine-Grained VT22 Alloy
Interlayer

Abstract: The structure and mechanical properties of the titanium alloy VT6 joint diffusion welded in vacuum at 820°C using an ultrafine-grained interlayer made of alloy VT22 in are studied after annealing at 900°C for 2 h. The heating-induced activation of diffusion processes is found to halve the number of micropores in the weld zone and to increase the tensile strength of the welded joint from 975 to 1108 MPa. The impact toughness of this joint after heat treatment corresponds to the initial impact toughness of the VT6 alloy.

• Effect of Small Alloying Additions on the Mechanical Properties of
Sintered Al–Sn Composites

Abstract: The Al–Sn composites prepared by liquid phase sintering of a mixture of alloyed aluminum and tin powders are studied. A small amount of alloying additions (Zn, Mg, Si, Cu) is found to promote substantial hardening of the aluminum matrix during its treatment by equal channel angular pressing, but these additions decrease the plastic properties. The maximum strength and the minimum plasticity are detected in the samples alloyed with 2% Cu.

• Effect of the Reverse Thermoelastic Phase Transformation on the Stress of
the Onset of a Structural Transformation in Titanium Nickelide

Abstract: The dependence of the stress of the onset of structural deformation of titanium nickelide on the degree of reverse phase transformation occurring after complete direct martensitic transformation is experimentally investigated. The experimental results are described qualitatively and quantitatively correctly in terms of a model, in which the maximum intrinsic inelastic strain intensity of the martensitic part of the representative volume of a shape memory alloy is used as an isotropic hardening parameter.

• Effect of the Phase Composition of Austenitic–Martensitic VNS9-Sh TRIP
Steel on the Characteristics of Dry Sliding Friction in the Tribocontact
with ShKh15 Steel

Abstract: The effect of the martensite phase content (from 0 to 50 vol %) on the hardness and tribotechnical properties of VNS9-Sh TRIP steel under conditions of dry sliding friction on ShKh15 steel (counterbody) is studied. The best combination of the hardness and the wear resistant is found in the steel with a martensite phase content of ≈32 vol %. The strength of VNS9-Sh steel is higher by a factor of more than two than that of 110G13L steel at comparable hardnesses and tribotechnical properties.

• Effect of Carbon and Nitrogen on the Stacking Fault Energy in Austenitic
Steels

Abstract: The data on the effect of carbon and nitrogen on the stacking fault energy (SFE) of austenitic steels are summarized. Threshold values of SFE characterizing the stability of austenite are given. The effective value of SFE for high-nitrogen austenitic steels is found to be 20–25 mJ/m2. At this value, these steels have the best combination of strength, ductility, and impact strength at a retained high stability of austenite to the γ–ε–α transformation during cooling and plastic deformation.

• Kinetics of Damage Accumulation in a D16ch Alloy during Static Loading

Abstract: The kinetics of damage accumulation in a D16ch sheet aluminum alloy (Al–Cu–Mg system) at various stages of static loading is investigated using a combined technique, which includes the detection of acoustic emission (AE) signals, structural studies, and the determination of electrical resistance and an eddy-current parameter. The dependences of these characteristics on the relative strain demonstrate the presence of four stages of specimen fracture. Correlation exponential dependences of the electrical resistance and the eddy-current parameter on damage are obtained, and they can be used to diagnose the state of the material.

• Sliding Friction of R6M5 Steel on Grade 45 Steel Using a Litol-24
Lubricant Modified by MoS2 Particles

Abstract: The influence of adding 10 wt % MoS2 particles to a Litol-24 lubricant on the sliding friction of R6M5 steel on grade 45 steel according to the roller–roller scheme is studied at a load of up to 800 N and a rotation speed of 1500 min–1. The determined general laws of sliding friction are shown not to change in comparison with the previously established ones. The dependences of the frictional force on the normal force (load) have two linear sections, in which the Amonton–Coulomb law is valid. In general, the generalized version of the Amonton–Coulomb law also holds true. The addition of MoS2 increases the lubricant viscosity and the bearing capacity of the lubricant layer. In the load range 510–725 N, the critical load increases by ≈1.6 times and the best antifriction characteristics are achieved.

• Texture and Anisotropy of the Mechanical Properties of MA2-1, MA14, and
Mg–5Li–3Al Alloys

Abstract: The anisotropy of the strength properties are compared with the averaged Schmid factors for the operating shear systems of textured pressed bars made of magnesium alloys MA2-1, MA14, and Mg–5Li–3Al in order to determine the ratios of the critical resolved shear stresses (CRSS) for the operating slip and twinning systems. In addition to the main deformation mode by basal slip in the MA2-1 and MA14 alloys, “tensile” {10 $$\bar {1}$$ 2}〈10 $$\bar {1}$$ 1〉 twinning and 〈 $$\bar {c}$$ + $$\bar {a}$$ 〉 slip are shown to be active. The ratio of the CRSS of these systems to the CRSS of the basal slip for the MA2-1 alloy is 1.7 and 2.2, respectively; for MA14, it is 1.5 and 1.8, respectively, which causes a lower anisotropy of the strength of the MA14 alloy and a more intense prismatic texture. For the alloy with lithium, the main deformation mechanism apart from basal slip is prismatic slip, for which the relative values of CRSS are 1.4 (which is lower as compared to other magnesium alloys). The results obtained make it possible to interpret the anisotropy of the properties in terms of Hill’s yield criterion, to calculate the corresponding anisotropy parameters, to plot yield locuses for the most common textures of semifinished products, and to show that the contribution of single-crystal anisotropy to the anisotropy of the strength properties significantly exceeds the contribution of the texture factor.

• Effect of Texture and Phase Composition on the Corrosion Properties of
Magnesium Alloys

Abstract: A quantitative method is developed to estimate the effect of texture and phase transformations on the corrosion properties of Mg–Al–Zn (MA2-1), Mg–Zn–Zr (MA14), and Mg–Nd–Zr (MA12) alloys. No significant effect of texture is found. A different character of changing the corrosion potential with the volumetric effect caused by the precipitation of intermetallic phases from a solid solution is revealed. The low corrosion resistance of the MA14 alloy is partially explained by the strong negative volumetric effect of MgZn2 precipitation, which is almost an order of magnitude higher in modulus than the volumetric effects of the precipitation of the Mg17Al12 and Mg12Nd phases in the MA2-1 and MA12 alloys with higher corrosion resistance.

• Sliding Friction of R6AM5 Steel on St3 Steel in Lubricating M14G2TS Oil
Containing a Hydrous Magnesium Silicate Powder

Abstract: The effect of addition of 1 wt % Mg6[Si4O10](OH)8 powder with a particle size of 10 or 20 μm to lubricating M14G2TS oil on the sliding friction of R6AM5 steel on St3 steel is studied in the load range 0‒1000 N. The additive is found to significantly increase the tribotechnical characteristics: the friction coefficient in the normal force range 500–1000 N decreases by 5.3–5.6 times, and the average friction force at a load of 800 N decreases by ≈2.8 times. The best results are obtained using an Mg6[Si4O10](OH)8 powder with a particle size of 20 μm. The dependences of the parameters of sliding friction of R6AM5 steel on St3 steel in the lubricating M14G2TS oil medium with and without the Mg6[Si4O10](OH)8 additive on the normal force consist of two linear sections and have an inflection point at a force of 300–500 N. In both sections, the Amonton–Coulomb law generalized with allowance for changes in frictional interaction conditions holds true.
