摘要：

The effects of temperature and Ti content on the deformation mechanisms of pure Zr and Zr-Ti alloys were investigated by transmission electron microscopy. The results indicate the existence of a relation between deformation-induced phase transformation from a hexagonal close-packed structure to a face-centered cubic structure and {10 (1) over bar1} deformation twinning. That is, when one is suppressed, the other will be promoted. The phase transformation was suppressed while the {10 (1) over bar1} compressive twinning was promoted with increasing the rolling temperature and/or Ti content. This can be attributed to the activation of basal <a> dislocations at high temperature and the increased stacking fault energy with Ti content.
