Abstract
In this paper the effect of carbon content on the fracture toughness changes with tempering, temperature of three Ni-Cr-Mo steels containing so-called strong background of other alloying elements is presented. The effect of tempering temperature on the steels' toughness was examined by the linear elastic fracture mechanics (K-Ic test). It was demonstrated that alloys containing 0.10 and 0.31% C are characterized by high fracture toughness and low ability to irreversible embrittlement after low - temperature tempering. The alloy containing 0.79% C is characterized by the lowest fracture toll toughness within the whole range of tempering temperature. Mechanical investigations were also supplemented with fracture surfaces observations. The obtained results are supposed to complement the existing software and d-bases pertaining to the quantitative effect of elements on steels' properties.
