Study on the Durable Factors of the Grain Size in 18CrNiMo7-6 by Heating and Cooling Method
Advanced Materials Research, 2011Study 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 ...

Study of Structural Inheritance of Austenite in Nb‐Microalloyed 18CrNiMo7–6 Steel
steel research international, 2018Structural inheritance (SI) is a phenomenon in which the newly formed austenite retains the prior austenite grain size, shape, and orientation of the previous martensitic, bainitic, or even tempered martensitic microstructure. The present work studies SI in 18CrNiMo7–6 steel with 0.08 wt% Nb and compares it with that in a similar but non‐microalloyed ...

SURFACE TOPOGRAPHY IMPROVEMENT OF 18CRNIMO7-6 STEEL USING THE TAGUCHI TECHNIQUE
The ball burnishing process provides a fast, cost-effective, and straightforward method to enhance the physical-mechanical properties and surface integrity of industrially manufactured parts. In this study, ball burnishing was applied to improve the surface topography of 18CrNiMo7-6 steel, with milling used as a pre-burnishing treatment.Dzierwa, Andrzej +3 more
