Study on the Microstructure and Fracture Mechanism of Stable β Phase Containing Tial Alloy

Abstract:

Study on the Ti-43Al-9V-0.3Y alloys forged microstructure, which added a large amount of β phase stable element. The influence on the mechanical properties and synusia cluster refinement about β phase is analyzed. The test of material static tensile at 700 °C and room temperature is conducted. The results show that the V elements urges the grain size α₂ and β phase formation, β phase can inhibit α grain growth effectively. At the same time, its deformation ability can increase the high temperature plastic of the material. Experiments show that the main form of alloy tensile fracture at room temperature was intergranular fracture. Hole proliferation and communicated with each other through layers of crack is the main characteristics of high temperature tensile fracture of the alloy.
