摘 要:本文采用L.Kaufman的计算方法,用规则溶体模型对稀土元素钇(Y)与难溶过渡族元素锆(Zr)、铪(Hf)的二元系:钇—锆,钇—铪进行了相平衡计算。并比较了此二系的计算相图和实测相图,二者符合良好。
Abstract: According to the regular soution approximation, the binary phase systems of rare earth (yttrium) and refractory transition metals (zirconium and hafnium) are calculated by the use of Kaufman’s method. The calculatedphase diagrams are compared with the experimental ones, and they are found in good agreement.
