TL;DR: In this article, a relatively dense equiatomic FeCrCoMnNi high entropy alloy with excellent mechanical properties is manufactured by LAM successfully and the effect of heat treatment on phase, microstructure, microhardness, residual stress and mechanical properties of as-built (AB) specimens are investigated.

TL;DR: In this paper, the effects of LSP scanning patterns on residual stress distribution and fatigue performance in Al 2024-T351 specimens were investigated and a 3D finite element analysis was performed to simulate the residual stress distributions.

TL;DR: In this article, the authors studied different dynamic characteristics of cavitation bubbles in infinite domain and attached to a solid wall and proposed an approximate linear relation to describe the relationship between the maximum bubble diameter and the ambient temperature.

TL;DR: In this paper, a novel compound strengthening method based on laser-induced peening and cavitation peening (LIPCP) was presented, and the surface roughness decreases with an increase in laser energies.

TL;DR: In this paper, the authors investigated near-surface residual stress and equivalent plastic strain distributions using finite element method for further understanding of laser shock peening induced plastic deformation and showed that residual stress at the topmost surface is sensitive to mesh size while they can be well predicted in the subsurface layer.
