Abstract: Two methods are employed, namely the Charpy impact test and a strain gauge technique, for the determination of the dynamic fracture toughnesses of CrNiMoV27 and CrNiMoV45 alloy steels under various impact loading rates and heat treatments. The results show that the dynamic fracture toughness KId is significantly affected by impact velocity and that tempering has a greater influence on KId than quenching. It is also shown that the alloy containing a greater amount of vanadium yields consistently a higher value of KId.
