摘要

The swelling behavior of 20％ cold-worked 15-15Ti steels with (0.23-0.40) wt％ titanium and (0.42-0.81) wt％ silicon content after heavy-ion beam irradiation has been investigated by transmission electron microscopy.The results show that 15-15Ti steel with higher titanium content displays lower swelling.As silicon content increases,the cavity size and the swelling of the 15-15Ti steels decrease obviously.Titanium and silicon may play important roles in suppressing the cavity nucleation and growth in 15-15Ti steel.
