Summary

The ductile-brittle transition temperature is the temperature at which the energy consumed up to the fracture suddenly decreases; this phenomenon is indicated by the transition temperature curve. The ductile-brittle transition temperature must be lower than the minimum exploitation temperature. For low temperatures, the authors used rolling plates, carbon manganese steels or low alloy steels with niobium, vanadium, molybdenum, aluminium and carbon-reduced content. The maintaining of the necessary weldability, while, at the same time, improving high-strength properties and tenacity at low temperature, can be obtained only through thermomechanical processing (controlled-rolling). The paper proposes a mathematical model that links ductile-brittle transition temperature and some technological parameters of thermomechanical processing.
