摘要
TiAl基合金的室温断裂韧性(以下简称断裂韧性)与室温显微组织(以下简称显微组织)密切相关。显微组织类型、晶粒尺寸大小、层片状晶团所占体积分数等都会影响断裂韧性。添加合金化元素、改变工艺路线等会对合金显微组织产生影响,从而影响断裂韧性。
The ambient fracture toughness of TiAl-based alloys have been studied as a
function of microstructure. Microstructure type, grain size, and volume fraction of lamellar colony may effect the fracture toughness of alloys. Adding alloy elements and varying process route may effect the microstructure of TiAl-based alloys, and consequently fracture toughness.
