M. Khantha et al., COOPERATIVE GENERATION OF DISLOCATION LOOPS AND THE BRITTLE-TO-DUCTILE TRANSITION, Materials science & engineering. A, Structural materials: properties, microstructure and processing, 234, 1997, pp. 629-632
A mechanism of cooperative generation of dislocation loops above a cri
tical temperature in loaded solids is described. We model the massive
dislocation activity which commences near the crack tip at the brittle
-to-ductile transition temperature in terms of this mechanism and show
that it can explain the main features of the transition. (C) 1997 Els
