TL;DR: In this article, a hybrid additive manufacturing process based on the integration of Laser Shock Peening (LSP) with selective laser melting (SLM) is described. But the authors do not consider the effect of residual stresses in the as-built (AB) state of SLM parts in the subsurface region.

TL;DR: In this paper, Li et al. investigated the influence of the main process parameters on the surface finish quality of the direct metal deposition (DMD) with laser, using an Yb-YAG disk laser, and a widely used titanium alloy (Ti-6Al-4V).

TL;DR: In this paper, a homogeneous distribution of tiny TiB whiskers within the Ti-6Al-4V α/β matrix, with a full solubilization of C for low B 4 C contents (0.5 and 1.5 ) and the formation of a small amount of globular TiC particles at higher B 4C content (3%).

TL;DR: In this paper, the influence of a pulsed laser regime on the surface finish induced by DMD on a widely used titanium alloy (Ti64) was investigated, and it was shown that using high mean powers improves surface finish but also indicate a specific effect of the laser operating mode: using a quasi-continuous pulsed mode instead of fully-cw laser heating is an efficient way for surface finish improvement.

TL;DR: In this paper, the effect of laser shock peening on the high temperature oxidation resistance of commercial pure titanium at high temperature (700 °C) was studied in long-time (3000 h) exposure under dry air.
