Abstract

The effects of the external stress on the displacive cubic (c) to tetragonal (t′) transformation, taking place during rapid quenching of ZrO 2 -Y 2 O 3 alloys by a hammer-anvil unit, were examined through the statistical analysis of the crystallography of the product phases. The initially formed c-phase had no strong texture with respect to the stress direction. However, specific t′ variants among crystallographically equivalent ones were formed preferentially. From these observations, it is concluded that the applied stress plays an important role on the deformation to change the lattice during the c → t′ transformation.
