Streszczenie
The effect of nitrogen and microalloying additions of V and V+Ti on the mechanical properties of heat treated 40Cr7 steel was investigated using four laboratory steels. Two variants of heat treatment were applied: normalizing and quenching with tempering at 600 °C. Mechanical properties - using tensile and notch toughness tests as well as hardness measurements - of heat treated steels were investigated. After normalizing higher values of tensile strength in non microalloyed steels were observed whilst after quenching and tempering V and V+Ti alloyed steels showed higher values of Rm.
