The results showed that the microstructure consists of α2, B2 and O phases and the formation of O phase can be effectively promoted by TCP with hydrogen. The volume fraction of O phase in the alloy was found to be increased with hydrogen content. Discussion on mechanism of the effect of TCP with hydrogen on microstructure of Super-α2 was also presented.
