Abstract
The conditions that determine the peak of flow stress in L1(2) alloys are explored in relation to the elimination of the Kear-Wilsdorf (KW) configurations. Two alternative hypotheses are explored according to w hether the Kear-Wilsdorf locks are destroyed by transformation and gli de in the primary octahedral plane or disappear upon activation of ext ensive cross-slip on the cube plane. It is shown that the consistency between present predictions and the experimental behaviour of a variet y of single crystals with L1(2) structure is qualitatively good.
