Abstract

TiAl is a L10 ordered alloy which exhibits a flow-stress anomaly peaking at approximately 600°C. In order to correlate the increase in flow stress with changes in deformation microstructure, the nature and dissociation of superdislocations are compared after deformation at 20 and 600°C. It is observ...
