Popis:	1. As-cast, the fracture of steel 45L is brittle (transcrystalline and intergranular fracture). In steels with vanadium there are more sections of brittle fracture with pearlite components. 2. The fracture of the quenched steel without vanadium is primarily transcrystalline, while the steel with vanadium and nitrogen has a predominantly dimpled fracture. 3. Alloying of steel 45L with small amounts of vanadium (0.06–0.2%) and nitrogen (0.025%) increases the strength 10–15% without lowering the toughness as-cast or after quenching.
