Abstract
In situ straining experiments in an Ni-25.9at.% Al alloy at room tempe rature indicate that the density of incomplete Kear-Wilsdorf locks is high during deformation. The model of mechanical properties which is b ased on their unlocking by an intrinsic cross-slip process is describe d, and compared with the alternative kink model. The results indicate that the alloy investigated has a higher complex stacking fault energy than stoichiometric Ni3Al. (C) 1997 Elsevier Science S.A.
