Method to produce fatigue resistant axisymmetric titanium alloy components

摘要

An improved process for producing near-alpha and alpha+beta titanium alloy axisymmetric components with high fatigue resistance which comprises the steps of: (a) providing a beta processed near-alpha or alpha+beta titanium alloy component; (b) torque deforming the component; and (c) alpha+beta recrystallization annealing the resulting torque-deformed component.
