合金鋼γ-α轉變形核驅動力及核心成分的計算

摘要: 采用Wagner的動力學模型,計算了含Mn,Si,Ni,Cr,Mo,Cu,V,Nb,W,Co等幾種合金元素(合金含量<7%)的多元系低合金鋼析出先共析鐵素體平衡及仲平衡下的臨界核心的成分和形核驅動力。設計了實用的計算程序。

Abstract: On the basis of Wagner's kinetic model, the compositions of critical nucleus and the nuclear driving forces of the precipitation of preutectoid ferrite in the conditions of equilibrium and para-equilibrium for polynary low-alloy steels, containing Mn, Si, Ni, Cr, Mo, Cu, V, Nb, W and Co (the total content<7%), were calculated. A pratical calculated programme was established.
