Effect of shot peening on the residual stress distribution in two commercial titanium alloys

The residual stress distribution in two commercial titanium alloys, the near-alpha IMI-685 and the alpha-beta IMI-318, have been determined using the method of drilling holes for the machined and polished as well as the machined, polished and shot-peened conditions. The residual stresses were always...

Summary:The residual stress distribution in two commercial titanium alloys, the near-alpha IMI-685 and the alpha-beta IMI-318, have been determined using the method of drilling holes for the machined and polished as well as the machined, polished and shot-peened conditions. The residual stresses were always compressive and their peak values for both alloys were similar. However, the stress distribution patterns were different and this could have implications for the fatigue behavior of the alloys. (Author)
