Single phase L1{sub 2} (Al,Cr){sub 3}Ti alloys show no anomalous strengthening at intermediate temperatures, but the strength rises rapidly at low temperatures. It is likely that a transition from SISF to APB superdislocation dissociation occurs with increasing temperature based on the more rapid decrease in APB energy compared to SISF energy because of entropy considerations. High strain hardening rates are suggested to arise in large part from the formation of large numbers of dipoles. Calculations of interaction forces illustrate the complexity of superdislocation interactions and provide a reasonable mechanism for initiating cross slip.
