Theoretical Calculation of β Transition Temperature of Ti-6Al-4V from Valence Electron Level

Abstract:

Based on the empirical electron theory of solids and molecules and the basic theory of the phase transformation of titanium alloys, a new method to calculate β transition temperature of titanium alloys is put forward after calculating the valence electron structure(VES) parameter n_A which is the covalence electron pairs on the strongest bond of alloy phases, the crystal cell weight of a and b phases in the structure, the compensation coefficient of the phase and the temperature coefficient of b stable element. After calculating we find β transition temperature of Ti-6Al-4V is 974.9 °C, the error of the theoretical calculation value and the experimental one(995 °C) is 2%, so it is feasible to calculate β transition temperature of the titanium alloys from covalence electron level.
