提高TiAl基合金室温塑性的方法

Methods of Improving Room Temperature Ductility of TiAl Based Alloys

摘要:

TiAl基合金具有密度低、高温性能好等优点，但室温塑性低一直是阻碍TiAl基合金应用的重要原因。本文总结了TiAl基合金的室温塑性的主要影响因素，以及通过添加合金化元素、改善加工工艺等方法来控制显微组织、提高TiAl基金合金的室温塑性的研究进展。

Abstract:

TiAl based alloys have an excellent potential because of their low density and good elevated temperature properties, but the chief roadblock to their application is poor room temperature ductility. This paper summarized influencing factors of room temperature ductility of TiAl based alloys and some research progress in improving room temperature ductility through adding alloy elements and varying process method which can control the microstructure of TiAl based alloys.
