摘要：

The morphology and formation mechanism of the substructure of martensite in TC21 alloy was investigated by XRD and TEM. The results showed that the martensitic transformation from beta to alpha '' occurs upon quenching after solution treatment between 960-1000 degrees C. The antiphase boundary (APB)-like structure was observed clearly in the alpha '' martensite plates. The APB-like contrasts exist along the (001) and (020) planes of alpha '' martensite. This APB-like structure of alpha '' martensite was identified as a kind of stacking fault with an APB-like morphology induced by martensitic transformation and not by order/disorder transition. During martensitic transformation, martensitic domains nucleate and grow, eventually encounter each other, resulting in the formation of the APB-like contrast.
