The results indicate that the orthorhombic alpha '' martensite and beta phase appear progressively with the increase of hydrogen concentration. On the other hand, hydrides with sizes of 2-5 nm are observed in the specimens containing more than 0.6 wt pct hydrogen. The formation of alpha '' and twins can be attributed to the internal stress caused by solid solution of hydrogen and hydrides precipitation.
