| Summary: | The effect of a 340°C heat treatment combined with an elastic tensile loading of 80 MPa on the impurity interface segregation in low-alloy CrMoV steel doped by boron has been studied by Auger spectroscopy. It was shown that the depth profile of phosphorus grain boundary segregation in the specimens subjected to the stressed state widened. The increase of the diffusivity coefficient of phosphorus for stressed specimens was obtained using McLean's segregation kinetics. In some cases, phosphorus segregation on the matrix—sulphide interface was found. |
