【Abstract】 The Ti 5.6Al 4.8Sn 2Zr 1Mo 0.32Si 1Nd(Ti 60) high temperature titanium alloy heat treated in β phase region was studied. The results of electronic probe analysis show that no elemental accumulation at grain boundaries is detected by EMP 810Q instrument. The main reason for obstruction of grain growth is that the rare earth rich phases hinder the movement of grain boundaries.更多还原
