γ-TiAl金属间化合物室温脆性及其影响因素

The Effect Factors and Brittleness of γ-type TiAl intermetallics Compound at Room Temperature

本文对影响γ-TiAl金属间化合物的室温脆性的因素从晶体结构尺寸、合金成分、变形位错、电子结构等四个方面进行了比较全面的阐述,得出结论:空间电荷的均匀分布有利于γ-TiAl合金室温塑性的改善。

This paper completely expatiates on the effect factors and brittleness of γ-type TiAl intermetallics compound at room temperature from four aspects: crystal structure dimension, alloy component, distortion dislocation and electron structure. The conclusion is drawn that proportional spacing of space charge is propitious for improving the room temperature brittleness ofγ-TiAl alloy.
