摘要
The structure and mechanical properties of steel with an elevated content of boron are studied after tensile tests at a high temperature. In its initial condition, the structure of the steel contains two types of borides [TiB2 and (Fe, Cr)2B] distributed uniformly in a ferritic matrix. The range of satisfactory process ductility is shown to be 1050 – 1150°C; at 1200°C the metal undergoes brittle fracture due to local fusion of individual regions of the structure.
