β Grain Growth Kinetics of a New Metastable β Titanium Alloy
Ti-Mo-Nb-Cr-Al-Fe-Si alloy is a new metastable β titanium alloy with excellent combination of strength and ductility.The β grain-growth exponent and the activation energies for β grain growth for the investigated alloy at specified temperature were computed by the kinetic equations and the Arrhenius-type equation.The rate of β grain growth decreases with elongating solution treated time and increases with the increasing solution-treated temperature.The β grain-growth exponents,n,are 0.461,0.464 and 0.469 at 1113,1133 and 1153K,respectively.The β grain growth activation energy is determined to be 274 KJ/mol.
