The dislocation structures of arc-melted,near-equiatomic TiAl alloys containing 1.5-2.0 wt.-%manga-nese were analysed and compared with those of binary TiAl alloy processed in a similar fashion.It was found that the pinning effect of a/6[112]partial dislocations was eliminated by Mn addition,as a result,the movement of a[101]and a/2[112]superdislocations and twinning and played an important role in the plastic deformation and increased the ductility of TiAl alloys.In addition,the workability of the Mn-ductilized TiAl alloy was evaluated with hot extrusion and forging. 展开更多
