TL;DR: In this paper, the AISI 304 was shot peened or deep rolled with different peening intensities, and rolling pressures, respectively, and the resulting near surface properties were characterized by cross sectioning transmission electron microscopy (TEM), residual stress and phase analysis as well as interference line halfwidth and microhardness measurements.

TL;DR: In this paper, high macroscopic residual stresses in PVD hard coatings up to about −10 GPa are caused by both the thermoelastic effects and grown-in defects, generated by fast particles during deposition.

TL;DR: In this article, the authors assume that in the case of sputtering Ar ions, metal ions with high kinetic energy push nitrogen atoms from regular lattice sites into tetrahedral holes of the rock salt type lattice and occupy the previous nitrogen sites, and that the incorporation of argon or metal atoms on nitrogen sites and the nitrogen interstitials, produce high compressive residual stresses.

TL;DR: In this paper, annealing of high speed steel and silicon substrates by reactive magnetron sputtering from a TiB 2 target with a stepwise increase of the nitrogen flow rate was investigated.

TL;DR: The microstructure of ultra-fine-grained (UFG) oxide-dispersion strengthened (ODS) copper, produced by mechanical alloying at low temperatures (cryomilling) and subsequent hot pressing under a protective argon atmosphere of copper powder and 3.5% of yttrium and calcium oxides, respectively, was examined by means of high-resolution scanning electron microscopy as discussed by the authors.
