β凝固钛铝合金相变行为研究进展
Research Progress in the Phase Transformation of β-solidifying TiAl Alloys
摘要
Abstract
β-solidifying titanium aluminium(TiAl)alloys are promising high-temperature structural materials and have great potentials in applications of the aviation,aerospace,and automobile industries.The phase transformation process ofβ-solidifying TiAl alloys from the molten state to room temperature is complex and directly affects their processability and performance.This article summarizes the major phase transformation types with respect to β-solidifying TiAl alloys,including β→α,β→β0,α→α+γ→α2+γ,and β0/α2→ω0.The effects of alloying elements,external stress and cooling rate on the microstructure and properties of β-solidifying TiAl alloys have been elaborated on the basis of the research progress of related mechanisms.The challenges and fundamental issues that need to be addressed for the industrial application ofβ-solidifying TiAl alloys are also discussed.关键词
