【摘要】 γ－ＴｉＡｌ基合金的工艺、组织、性能三者关系极其密切，显微组织的控制是改善γ－ＴｉＡｌ基合金性能缺陷的重要途径之一．而适当的加工工艺又是实现显微组织控制的手段．按照工艺、组织、性能这个关系，本文旨在阐述几种典型工艺下的γ－ＴｉＡｌ基合金的显微组织特征，为试图通过组织控制来改善γ－ＴｉＡｌ基合金的性能缺陷提供参考．更多还原

【Abstract】 The relationships among Processing-Microstructure-Property are very close. The mi-crostructural control is one of the most important methods to improve the drawback of me-chanical properties of γ-TiAl base alloys. According to the relationships of Processing-Micro-scructure-Property, this paper mainly elucidate the microstructural features of γ-TiAl base alloys under several typical processings and provids the references to improve its mechanical properties using microstructural control.更多还原
