Originální abstrakt
Fracture experiments on a polycrystalline Fe-2.3 mass V – 0.12 mass% P alloy at room temperature have shown that the fracture mode was directly related to the grain boundary segregation of phosphorus. As expected, the ratio of intergranular brittle fracture increased with increasing grain boundary concentration of phosphorus for all annealing temperatures. Comparison of the experimental data with theoretical simulations revealed that the intergranular fracture spreads along grain boundaries containing more than 17 at% of segregated phosphorus. The mean value of the surface energy of segregated intercrystalline facets was found to be of 19 J/m2. This value is comparable with the surface energy of brittle cleavage in ferrite at very low temperatures as well as with that determined for the Fe-2.3 mass% Si – 0.12 mass% P alloy
