[求助] 固溶Nb的强化增量怎么计算呢?是多少?已有1人参与

如题!一般合金元素的固溶强化增量为:4570[C]+67.6[P]+84[Si]+32[Mn]+11[Mo](参考钢铁材料中的第二相),但没见过Nb的固溶强化增量关系式!求助!Nb前面的系数是多少呢?能给我参考文献吗?

Nb will form carbide or nitride in the steel. during hot rolling process strain induced precipitation happens. Nb is rarely in the state of solid solution. the Nb is employed in steelmaking not for solid solution strengthening but for precipitation hardening by controlled rolling and controlled cooling

谢谢!美女,但我的钢是轧后快冷,抑制的Nb的析出,大部分Nb是固溶态的~~~~
