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

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

The Synchrotron Radiation for Steel Research
Advances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016 The synchrotron X‐ray radiation is a great tool in materials characterization with several advantageous features. The high intensity allows clear interaction signals and high energy of X‐ray yields higher sampling volume. The samples do not need extra preparation and the microstructure is therefore not affected. With the tunability of the X‐ray energy,
