TEM evaluation of steel nanocrystalline surfaces obtained by severe shot peening

TEM analysis was performed in this study to analyze microstructural changes of a quenched and tempered 39NiCrMo3 low alloy steel as a function of the kinetic energy induced by means of different shot peening treatments: conventional (CSP) and severe (SSP). Residual stresses and microhardness evoluti...
