The elasticity of the hardened layer under pendulum surface plastic deformation is determined. Calculations are given using computer modeling Ansys 19.1 to estimate influence main technological parameters and modes SPD (Surface deformation) by amount metal rate upward gradient, which makes it possible establish actual tension ensure accuracy diametrical dimensions parts. dependence elastic rise...

equal channel angular rolling (ecar) process is one of the methods that have been used to makeultra-fine materials by imposing severe plastic deformation. after repeating the process severaltimes, a large effective strain is applied to the sample that can cause decreasing the grain size andimproving the mechanical and physical properties of the metal. in this study, thermal conductivityof the s...

the full annealing aa6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ecap) and cold rolling (cr) in order torefine its microstructure and to improve its mechanical properties. according to the results of hotand cold tensile tests, the combination of ecap and cr significantly affected the final strengthand ductility of studied...

The effect of pre-existing nano sized precipitates on the mechanisms and rate of grain refinement has been investigated during the severe plastic deformation. A binary Al–0.2Sc alloy, containing coherent Al3Sc particles, of 3.62 nm in diameter has been deformed by accumulative roll bonding up to 10 cycles. The resulting deformed structures were quantitatively analyzed using electron backscatter...
