Abstract

Microstructural examination of castings of the γ-TiAl+α2-Ti3Al alloys depending on aluminum content, alloying additions, and cooling rate has been carried out. Experimental findings allowed a novel concept of designing of γ-TiAl+α2-Ti3Al alloys to be proposed. The concept is addressed on the production of cast alloys with a chemically homogeneous fine-grained microstructure and improved workability.
