Study on Microstructure Evolution of TA1 during Plane Compression and its Similarity to Power Spinning

Abstract

The hot power spinning process of TA1 has been studied on the base of isothermal plane compression model in this paper. The microstructures of spun workpieces and plane compression specimens are analyzed and the microstructure evolution mechanism has been investigated. The results reveal that the microstructure evolution has similar mechanism between power spinning and plane compression. Plane strain compression can be used to predict and control the microstructure of as-spun TA1 workpiece.

Deformation mechanisms based on the multiscale molecular dynamics of a gradient TA1 titanium alloy

“…The TA1 (industrial pure titanium) titanium alloy is widely used in industries such as aerospace, defense, and marine engineering. [2][3][4] However, the opposing relationship between strength and ductility greatly limits its engineering application potential and value. By endowing the TA1 titanium alloy with a functional gradient structure, it is possible to obtain a new type of titanium alloy with high strength and high ductility.…”
