Stress-Induced Stacking Faults and Their Interference with Slip on Intersecting Planes in Copper-Aluminium Alloys

Abstract

AbstractAttention is directed to the extension of a dislocation by the acting stress in metals having a low stacking-fault energy. It is shown that stress-induced stacking faults impede the movement of dislocations on intersecting slip planes, causing overshoot in copper-aluminium single crystals when tested in tension.
