Abstract
For Ti3Al intermetallic with the D019 superlattice, the computer-aided simulation of the superdislocation core structure in the basal, prismatic, and type I and type II pyramidal planes is performed. A model of thermally activated transformation of 2c + a glissile edge superdislocations into dislocation barriers in the pyramidal planes is used to account for the anomalous temperature dependence of the yield stress of single-crystal Ti3Al compressed in the [0001] direction.
