Study on the Durable Factors of the Grain Size in 18CrNiMo7-6 by Heating and Cooling Method
Advanced Materials Research, 2011 Study researches durable factors of the grain size in 18CrNiMo7-6 by heating and cooling method. Results show that alloying elements Nb and Al have a strong pining effect on the grain boundaries, Al/N ratio between 2.0-2.5 can promote the grain not to grow up for a long time, and refine grains significantly with furnace heating and after carburizing ...

Tailoring the Hardening Behavior of 18CrNiMo7‐6 via Cu Alloying
steel research international, 2015 In order to improve the rolling contact fatigue (RCF) behavior of gear steels, a concept to increase their damage tolerance is developed alternatively to the conventional approach of improving the degree of steel cleanliness. For that purpose, Cu is used as a main alloying element in order to trigger the precipitation of nano‐sized Cu precipitates ...
