| 英文摘要 | The high temperature beta/B2 phase field of Ti3Al-Nb based alloys was rarely studied due to limitation in experimental technique, but different states of this phase field lead to difference in subsequent phase transformation path and resulting microstructure. By controlling the heating temperature and dwell time of alpha(2)' -> beta/B2 transformation and subsequent cooling rate, we achieved a new microstructure consisting of domains of the B2 phase with alpha(2)' martensite occupying the disordered BCC domain walls, effectively forming a pseudo sub-grain microstructure. It is shown that the domain walls evolved from the disordered beta phase in the beta/B2 phase field. Such pseudo sub-grain boundaries refine the prior beta grains by subdividing them into smaller alpha(2) colonies that form during subsequent heat treatment in the alpha(2)' + beta/B2 phase field upon reheating, and improve the mechanical properties of the alloy. |
