V-N合金在非调质钢的应用探讨

Application and analysis of VN alloy in non-hardening and tempering steel

非调质钢中增氮，改变了钒在相间的分布，促进V（C，N）析出，使析出相的颗粒尺寸明显减小，从而增强了钒的沉淀强化作用，大幅度提高钢的强度。

An enhanced nitrogen content promotes the precipitating of V ( C , N ) and decreases the particles size of V ( C , N ) precipitates , hence increases precipitation strengthening effect of vanadium .
