Abstract
A technique allowing the rapid evaluation of the impact strength KCV of steels within the ductile–brittle transition temperature range is proposed in this work. A unified diagram of impact strength for different steels within the ductile-brittle transition range is built. A linear dependence \(\frac{{KC{V_T}}}{{KC{V_P}}} = f\left( {\frac{{KC{V_T}H{B_p}}}{{KC{V_T}H{B_T}}}} \right)\) is established within the temperature range of 77–473 K, where the subscripts T and p refer to the temperature of the impact strength to be estimated and the end temperature of the Peierls–Nabarro plastic deformation mechanism accordingly. The method for prediction of the impact strength is developed on the basis of the above diagram. It enabled us to reduce the number of needed tests and to gather information unavailable before because of the limited volume of material.
