Fe-V 合金在 NH3 气氛中氮化会形成具有相当高硬度值的氧化皮。该标尺的硬度显示出与未氮化铁素体基体的硬度的逐渐变化，特别是在低钒合金中，例如含有 1.06%V 的合金。这种硬度过渡区的形成可以用析出物密度随时间增加来解释，这又是VN析出物在铁素体中高溶解度的结果。实验数据表明，沉淀过程始于相干沉淀物的形成，然后该沉淀物尺寸增大并在进一步退火时变得不相干。与额外氮原子形成共格析出物导致铁素体晶格膨胀。 （1975 年 6 月 10 日收稿）
The nitriding of Fe-V alloys in NH3 atmosphere results in the formation of a subscale with rather high hardness values. The hardness of this subscale shows a gradual change to that of the unnitrided ferrite matrix especially in low vanadium containing alloys such as those that contain 1.06%V. The formation of such a hardness transition region is explained in terms of the increase in precipitate density with time, which in turn is the result of the high solubility of VN precipitates in ferrite. The experimental data indicate that the precipitation process starts with the formation of coherent precipitates which then grow in size and become incoherent upon further annealing. The formation of the coherent precipitates with extra nitrogen atoms results in the expansion of ferrite lattice. (Received June 10, 1975)
