Texture Gradients in Shot Peened Ti-2.5Cu

Abstract

Shot peening is a mechanical surface treatment having a deep impact on the materials which generates beneficial near-surface plastic deformation resulting in changes in peening texture characteristics. The present study aims to investigate the texture gradients in the solution treated (SHT) Ti-2.5Cu after shot peening with Almen intensity of 0.20 mmA. Due to a high transmission and a large beam cross-section of neutrons, texture analysis by neutron diffraction has become the standard method to investigate bulk textures. In contrary, the penetration depth of conventional X-rays is a relatively smaller than that of neutrons. Therefore, it is able to measure texture gradients in some hundred microns from the surface.
