Prediction of the formation of carbide network on grain boundaries in carburizing of 18CrNiMo7-6 steel alloys

Surface and Coatings Technology, 2021
Abstract With the increasing surface carbon content during the carburizing process, undesirable carbide networks are generally formed on the surface and in the near-surface region of the mechanical parts composed of plain low carbon steels. Therefore, it is of great significance to predict the formation conditions of carbide networks in advance and ...

Determination of the mechanical properties of surface-modified layer of 18CrNiMo7-6 steel alloys after carburizing heat treatment

International Journal of Mechanical Sciences, 2018
Abstract A surface-modified layer (SML) can enhance the fatigue life of key components. Material in a SML is inhomogeneous in the depth direction. Therefore the test method for this type of material should differ from that for a homogeneous material.
