Resumen:
The laser shock peening (LSP) is a new technique that improves the fatigue life of metals components by inducing deep compressive residual stresses through the surface. However, the beneficial effects of LSP depend on the persistence and stability of such residual stress fields under cyclic loading and temperature. Moreover, if absorbent coatings (typically a black paint) are not used in LSP operation, thermal effects can occur on the metallic substrate.The purpose of this work is to study in a superferritic stainless steel UNS S 44600 the effect of LSP, without protective coating, on the low cyclic fatigue behavior at room temperature.
