通过等温锻造方法对Ｔｉ－４７Ａｌ－５（Ｃ＋Ｖ＋Ｍｏ＋Ｎｂ）（ａｔ％）合金进行组织控制。研究发现，由于合金在凝固过程中存在两个包晶反应，导致枝晶间铝含量的分布极不平衡，从而使铸锭组织不均匀，含有大量的γ＋α２片层组织。在热加工中，片层组织在大变形量下发生剪切变形或严重弯曲。剪切变形组织沿平行于片层边界作用，使各片层团间产生大量再结晶晶粒并呈无序生长；而由于γ和α２取向关系发生畸变，γ和α２由片层形式趋向于等轴。本研究还对γ－ＴｉＡｌ合金再结晶机理进行了讨论。
Tissue control of Ti-47Al-5 (C + V + Mo + Nb) (at%) alloy was carried out by isothermal forging method. It is found that there are two peritectic reactions in the solidification process, resulting in a very unbalanced distribution of aluminum content between the dendrites. As a result, the ingot structure is not uniform and contains a large amount of γ + α2 lamellar structure. In thermal processing, lamellar structures undergo shear deformation or severe buckling under large deformations. Shear deformation of the organization parallel to the edge of the sheet boundary, so that the formation of a large number of recrystallized grains between the groups and the growth of disorder; and due to γ and α2 orientation distortion, γ and α2 form from the lamellae tend to axis. The research also discussed the recrystallization mechanism of γ-TiAl alloy.
