Abstract
Laser shock peening is a new and high technology with application value and development prospect. It can effectively improve the fatigue resistance, wear resistance and corrosion resistance of metal materials. In this paper, two-phase titanium alloy TC17, which is widely used in aerospace field, is studied by finite element method. The effects of different laser shock paths on the deformation and residual stress distribution of materials are studied. The results show that the large-area complex path strategy laser shock peening has a certain influence on the deformation and residual stress of TC17. Single-sided, double-sided simultaneous and double-sided non-simultaneous laser shock peening have a great influence on the residual stress size and distribution. Reciprocating path laser shock peening provides less distortion and higher residual stress than a zigzag path.
