用钒微合金化热轧钢及正火钢可提高强度性质。此时,主要是在铁素体基体中析出细而分散的碳化物微粒起强化作用。 在少珠光体铸钢中,添加钒产生的强化作用波动很大,在许多情况下,花费昂贵稀缺的钒而没有提高钢的强度,这是完全可能的。因此,弄清楚添加钒强化少珠光 Vanadium microalloyed hot-rolled steel and normalized steel can improve the strength properties. At this point, mainly in the ferrite matrix precipitated fine and dispersed carbide particles play a reinforcing effect. In less pearlitic cast steels, the strengthening effect of the addition of vanadium is very variable and in many cases it is quite possible to spend expensive and scarce vanadium without increasing the strength of the steel. Therefore, make it clear that adding vanadium to strengthen less pearlescent
