由于γ-TiAl合金低密度和高温时的高比强度,因此很有希望在航空和汽车工业的高温领域得到应用。但该合金低的延展性和抗氧化能力限制了它的实际应用。研究发现,添加第3组元可以提高TiAl合金的工程性能。因此,人们相继开展了 Due to the low density of γ-TiAl alloys and the high specific strength at high temperatures, there is great promise for applications in the high temperature areas of the aerospace and automotive industries. However, the low ductility and oxidation resistance of the alloy has limited its practical application. The study found that adding the third component can improve the engineering properties of TiAl alloy. Therefore, people have carried out one after another
