快速凝固改善钛合金性能因为钛合金及如ＴｉＡｌ一类的金属间化合物具有低密度，所以在航空航夭领域具有诱人前景。过去人们常用铸锭冶金（ＩＭ）工艺制作低密度的钛合金，然而未来材料性能的改善，不太可能再依赖于传统的合金化、机加工、热处理对显微结构的改善来提高，... Rapid solidification improves the performance of titanium alloys Because titanium alloys and intermetallics such as TiAl have a low density, they have attractive prospects in the field of aeronautical navigation. In the past, ingot metallurgy (IM) processes were commonly used to make low-density titanium alloys. However, future improvements in material properties are less likely to be relied on by conventional alloying, machining, and heat treatment to improve the microstructure. .
