研究了三元碳铁基合金Fe-3%Cr-0.345%C在渗氮过程中的相变，旨在更好地理解残余应力的产生和演变。在扩散区的三个不同深度处，研究了Cr 7 C3碳化物和CrN氮化物的析出、诱导体积变化和力学性能之间的关系。残余应力的松弛通过根据氮的扩散以及碳的扩散的相变而产生。
Phase transformations during nitriding of a ternary carbon iron-based alloy Fe–3%Cr–0.345%C were studied, aiming for a better understanding of residual stresses generation and evolution. The relationship between the precipitation of Cr7C3 carbides and CrN nitrides, the induced volume change and the mechanical properties were investigated at three distinct depths of the diffusion zone. The relaxation of residual stresses arose through phase transformations according to the diffusion of nitrogen but also of carbon.
