Deformation Influence of Shot Peening on Thin-wall Titanium Alloy Blade
摘要
Abstract
Objective To research the deformation influence of shot peening on thin-wall titanium alloy blade and find methods to resolve the deformation problems about shot peening. Methods Thin-wall titanium alloy blade was shot peened and the size and dimension of blade were measured. Results The deformation value and tendency were basically the same with various shot peen paths if the intensity and coverage were the same. Blade showed nearly no deformation if the intensity of the second shot peening was the same as the first shot peening. The intensity of the second shot peening must be higher than that of the first shot peening in order to cause deformation of the blade. The surface residual stress of the blade decreased after vacuum distressing, but the deform-ation value and tendency were basically the same as those of the blade that did not undergo vacuum distressing. Conclusion Based on the situation of blade deformation after shot peening, pre-deformation and shot peening straightening methods were recommended to make the size and dimension of blade meet the requirement of drawing.关键词
