Influence of the Deformation Parameters of a Low-cost Titanium Alloy on Structure

Abstract

By the research in the thermodynamic simulation of a new kind of low-cost Titanium alloy-Ti8LC, The temperature, speed and degree were studied to prove what infection it take to the Micro-structure. The test make clear that the influence of temperature was the most important parameter to the alloy, when it under 1000℃, it appears two-state structure, it is propitious to the combination properties, and when it above 1000℃, it appears lamellar structure, holds high strength but low extensibility. Comprehensive consideration with the resistance to deformation, the velocity in the deformation cannot take too fast, and the degree adapted to 40％～60 ％. This can gain favorable capability.
