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.
