ABSTRACT:
A method for producing Ti alloy plates, comprising heating an .alpha.+.beta. Ti alloy ingot to a temperature within the .alpha.+.beta. two phase range, forging or rolling said heated alloy ingot to reduce it more than 30% whereby strain energy accumulates in said ingot as it is being reduced, and reheating said reduced ingot containing said accumulated strain energy to a temperature of the .alpha.+.beta. phase range and then hot rolling said reheated reduced ingot so that it is further reduced in an amount more than an additional 30% whereby said accumulated strain energy accelerates recrystallization during said hot rolling to produce a uniform alloy structure, said heating and reheating being carried out in an atmosphere having not more than 0.02 atm oxygen partial pressure.
