BANDED MICROSTRUCTURE IN FORGED 18CrNiMo7-6 STEEL

open access: yesMetallurgy 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

Effects of profile errors on lubrication performance of helical gears [PDF]

open access: yes, 2017
Analysis of the elastohydrodynamic lubrication (EHL) of gears generally assumes that the tooth flanks are smooth surfaces. There is considerable interest in establishing the extent to which smooth surface analyses are distorted by the presence of surface
