BANDED MICROSTRUCTURE IN FORGED 18CrNiMo7-6 STEEL
Metallurgy and Foundry Engineering, 2009 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

Gradient microstructure and microhardness in a nitrided 18CrNiMo7-6 gear steel [PDF]
IOP Conference Series: Materials Science and Engineering, 2017 A commercial gear steel (18CrNiMo7-6) containing a tempered martensite structure was nitrided using a pressurized gas nitriding process under a pressure of 5 atm at 530 °C for 5 hours. The mechanical properties and microstructure of the nitrided sample were characterized by Vickers hardness measurements, X-ray diffraction, and backscatter electron ...
