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
