Abstract
Transmission electron microscopy observations of extended nodes in Cr2 Nb compressed at 1400 and 1500 degrees C have been used to obtain a va lue of gamma = 25 mJ m(-2) for the stacking-fault energy above the duc tile-to-brittle transition temperature of 1200 degrees C. Such a modes t value for gamma may help to explain the significance of deformation twinning and the formation of polytypic structures in this compound.
