A Review on Mechanical Properties of Metallic Materials after Laser Shock Processing

Abstract

Surface treatment technologies have become more and more important in industry to cut costs and avoid the need for expensive materials. As demonstrated a few decades ago, laser shock processing (LSP) is now emerging as a viable surface treatment technique. This technique improves the mechanical properties by inducing a compressive residual stress field. This paper presents the operating principles of LSP and a review of mechanical properties after laser shock processing.
