Although the Bauschinger effect has been investigated in some detail various materials, number of articles on grain size is extremely limited, and current nanostructured materials it practically absent. Since such are considered as promising for structural applications, important to understand their mechanical behavior under conditions changing direction deformation, and, therefore, necessary s...

We present an experimental investigation of the effects of surface passivation, film thickness and grain size on the plastic behavior of freestanding Cu thin films. The stress–strain curves of the films are measured using the plane–strain bulge test. Films with a passivation layer on one or both surfaces have an offset yield stress that increases significantly with decreasing film thickness; th...

The contribution of kinematic hardening to the overall strain a high entropy alloy (HEA) was investigated for first time ever. It assessed single-phase equiatomic CoCrFeMnNi based on study Bauschinger effect. observed occurrence back stresses signifies substantial hardening. We attribute it low probability cross-slip in this HEA which, however, rises process straining. A model that captures men...
