Research Progress of Titanium Matrix Composites Sheet Rolling

钛基复合材料中的增强相极大增加了其热加工难度,导致大变形或大尺寸高性能钛基复合材料板材的制备困难。从钛基复合材料板材发展现状出发,围绕其热轧制技术,分析了轧制温度、变形量及轧后热处理工艺对板材微观组织演变和力学性能的影响规律,重点分析了轧制过程和热处理过程增强相与基体组织之间的相互作用。最后指出当前钛基复合材料板材轧制研究存在的不足及未来的发展趋势。

The reinforcements in titanium matrix composites make hot working much more difficult, thus making high-performance titanium matrix composites sheet with considerable deformation or large size difficult to prepare. Based on the recent advances in titanium matrix composites sheet and its hot rolling technology, the effects of rolling temperature, deformation, and post-rolling heat treatment process on microstructure evolution or mechanical properties were respectively analyzed, with a focus on interactions between reinforcements and matrix microstructure during rolling and heat treatment. Finally, the deficiencies of current research and the future prospects of titanium matrix composites sheet rolling were pointed out.
