Fatigue fractures, a persistent challenge in the aerospace industry, are often induced by the demanding operating conditions and the multifaceted stress states to which aviation engines are subject. These fractures not only compromise the structural integrity of aircraft components but also significantly undermine the safety and reliability of the entire aircraft system. In addressing this issue, Laser Shock Processing (LSP) is recognized as a cutting-edge solution. This technology, by creating a microstructural deformation layer exceeding 1 mm in depth and inducing a residual compressive stress layer at the material‘s surface, significantly enhances the mechanical properties of metals. Consequently, the fatigue life of critical components is markedly extended, offering a robust defense against the onset of fatigue fractures.
