Ni-Cr-Mo steels with varying values of carbon equivalent were chosen to investigate the effects of resulting carbides on temper embrittlement mechanisms. Each composition was subjected to a typical industrial heat treatment followed by previously established embrittlement and recovery treatments. Microstructural features such as carbide morphologies and distribution, as well as carbide volume fraction were investigated using scanning electron microscopy and quantified using image analysis software. Mechanical characterization was completed via tensile and Charpy V-Notch testing. The influence of carbide type, composition, and distribution within the bulk and on the grain boundaries on the mechanisms of temper embrittlement will be discussed.
