Abstract

This study reviews the current status of the understanding and development of laser shock peening(LSP) on various metals. The influence of processing parameters on residual stresses, microstructure and properties are discussed. Special emphasis is placed on analyzing their underlying interrelationship between the LSP induced modifications. Finally, recommendations for further study are listed. Results indicate that the combination of uniquely flexible process and excellent performance makes the laser shock peening an attractive candidate for surface optimization applications.
