Patent ID: 11148207

Abstract:
A laser shock peening method for an additive manufactured component of a double-phase titanium alloy is provided. First, a three-dimensional digital model of a complex component is obtained, and the model is divided into a plurality of slices; a forming direction of a formed part in an additive manufacturing process is determined according to a stress direction of the additive manufactured component in an engineering application; then, the component of the double-phase titanium alloy is formed and manufactured by selective laser melting, and orientations of a C-axis of an α phase is allowed to be consistent through adjustment and control; and finally, laser shock peening is performed on all outer surfaces of the high-performance additive manufactured component of the double-phase titanium alloy by inducing a high-intensity shock wave to act in an acting direction which forms an angle in a predetermined range with the C-axis of the α phase.
