Popis:	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 β to α″ occurs upon quenching after solution treatment between 960–1000 °C. The antiphase boundary (APB)-like structure was observed clearly in the α″ martensite plates. The APB-like contrasts exist along the (001) and (020) planes of α″ martensite. This APB-like structure of α″ 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.
