摘要: 采用現有計算方法,對低碳鋼中鈮的碳氮化物NbC_xN_1-x中的x值進行了理論計算.計算結果表明,NbC_xN_1-x中的x值主要受成分和溫度的影響,隨鋼中C含量增大、N含量減小而增大,隨溫度的升高而減小之.通過與相關實驗結果比較發現:在一定的成分、溫度范圍內計算結果與之符合良好;對于超出該范圍的Nb微合金化低碳鋼,計算結果可作參考.給出了溫度和范圍成分分別為1050～1250℃和0.10%C-0.005%N-0.20%Nb～0.20%C-0.005%N-0.20%Nb.

Abstract: For NbC_xN_1-x in low-carbon microalloyed steels,x values in the formula are calculated by existing methods.As shown in the calculation results,the x values are mainly influenced by temperature and composition.The x values increase with increasing C content and decreasing N content,as well as decreasing temperature.It is indicated that in a certain range of composition and temperature,the calculation results is in good agreement with experimental data from related references.On the other hand,for the steel with composition over the range,the calculation results should be treated as a reference only.The ranges of temperature and composition are 1050 to 1250℃ and 0.10%C-0.005%N-0.20%Nb to 0.20%C-0.005%N-0.20%Nb,respectively.
