Abstract
In this paper, we investigate how laser-shock peening and deep rolling affect the cyclic deformation and S/N-behavior of austenitic stainless steel AISI 304 at elevated temperatures (up to 600 °C). The results demonstrate that laser shock peening can produce similar amounts of lifetime enhancements as deep rolling. The cycle, stress amplitude and temperature-dependent relaxation of compressive residual stresses is more pronounced than the decrease of near-surface work hardening.
