Effect of shot peening on the residual stress and mechanical behaviour of low-temperature and high-temperature annealed martensitic gear steel 18CrNiMo7-6 [PDF]
A martensitic gear steel (18CrNiMo7-6) was annealed at 180 \ub0C for 2h and at ∼ 750 \ub0C for 1h to design two different starting microstructures for shot peening.

BANDED MICROSTRUCTURE IN FORGED 18CrNiMo7-6 STEEL
18CrNiMo7-6 steel, after hot forging, exhibits a distinct banding of ferritic-pearlitic microstructure, probably related to the segregation of alloying elements during the ingot crystallization. The heat treatment allowing to obtain bainitic microstructure in this steel is described in the paper. The obtained bainitic microstructure exhibits only
