Abstract In this work, Ti6Al4V ELI samples were fabricated with previously optimized
parameters by selective laser melting (SLM) and then heat-treated under vacuum (HT) or hot …

The laser shock peening (LSP) process using a Q-switched pulsed laser beam for surface
modification has been reviewed. The development of the LSP technique and its numerous …

The conventional techniques exhibit several limitations including weak bonding strength,
shrinkage defects, micro-delamination and porosity, which duly have a synergistic effect on …

A detailed analysis has been conducted of Ti–6Al–4V processed by metallic shot peening
and laser shock peening. Analysis by incremental hole drilling, electron backscattered …

Additive manufacturing (AM) can be seen as a disruptive process that builds complex
components layer upon layer. Two of its distinct technologies are Selective Laser Melting …

Micro-structural evolution and grain refinement in ANSI 304 stainless steel subjected to
multiple laser shock processing (LSP) impacts were investigated by means of cross …
