Description
Summary:Work-hardening of alpha -phase Cu -- Al solid solutions of Al concentration up to 14 at.-% was studied for temp. 4.2 to 300 deg K. A substantially nonmonotonous concentration dependence has been established for a number of work-hardening parameters that tends to increase at lower temp., and correlation has been found between temp. dependences of the yield stress and activation volume. The change in the density of mobile dislocations during strain rate cycling has been estimated and found to increase with temp. reduction.12 refs.--AA
