Nitriding can significantly increase the load carrying properties of gears. While the diffusion layer is primarily responsible for improving the tooth root and flank load carrying capacity, the compound layer mainly determines the tribological proper

Damages to case-hardened components are often associated with the phenomenon of hydrogen embrittlement due to their specific fracture pattern. In the present work, the effects of the case hardening process on the hydrogen content in the material were

Nitriding is a widely used treatment to increase the performance of unalloyed and alloyed steels. Because nitriding majorly affects the hardness of the surface region of the material it is common to perform a quenching and tempering treatment before

Heat treatment simulation can be an effective tool aimed at solving failure problems economically. However, the quality of numerical predictions depend on the quality of the applied models. It is well know that during quenching cracks may form due to
