Abstract

Abstract

The third generation TiAl based intermetallic compounds (β-solidifying TiAl alloy) have a wide application in aerospace, automobile manufacturing and other advanced fields due to their excellent hot workability. However, the introduction of high temperature β phase not only improves the hot deformation capacity of the alloy, but also makes the microstructure evolution and performance optimization more complex. Meanwhile, the development of industrialization is relatively slow because of the influence of alloy composition and poor intrinsic brittleness. This paper provides an overview of the processing and working technologies, progress of microstructure, properties and the current industrialization situation of the typical β-solidifying TiAl alloy. The technology and cost advantages of processing and working were analyzed. The effect mechanisms of alloy composition, hot deformation, heat treatment and alloying on microstructure evolution and property optimization were clarified, and the restrictions and future prospects of industrialization were pointed out.
