... properties. In this work, laser shock peening (LSP) treatment on both SLM and cast aluminum A357 alloys are compared with regard to the development of beneficial near-surface compressive RS. Experiments are conducted using high energy nanosecond pulsed laser, together with a fast photodetector connected to a...

..., the use of laser shock peening (LSP) along with an automatic X–Y table proves to be an attractive and reliable method for producing microdent arrays with enhanced surface integrity. Surface topography and profiles of the fabricated microdent arrays on polished Ti–6Al–4V have been characterized. The...

...Xiangqun Zhu; Ming Zhou; Qixun Dai; Gary J. Cheng In order to study the deformation mechanisms during ultrahigh strain rate deformation of face centered cubic metals, laser shock peening of a 304L stainless steel is systematically investigated. Two deformation modes—microtwins and microbands—and...

...Yongxiang Hu; Zhenqiang Yao; Jun Hu Laser shock peening (LSP) is an innovative surface treatment technique similar to shot peening. An analytical model to predict the residual stress field can obtain the impact effect much quickly, and will be invaluable in enabling a close-loop process control in...
