It was shown that the equation is also available to Po, its C_α =0.21 at.-％ and the effective electric charge z~*=5.26. The maximum solubility C_β of S, Se, Te or Po in β-Ti was estimated to be 0.13, 0.24, 0.29 or 0.32 at.-％ respectively by the correlation between C_β and C_α. Thevariations of C_α and C_β of the elements of group VIA are controlled by nonmetallicity and the difference between the radii of atoms of these elements and Ti, and mainly by their non-metallicity. C_α and C_β have good linear relationships with the difference between electronegativity, the ratio of electric charge and radius of Ti or these elements, the ratio of electric charge and radius of these elements and the difference between atomic radii of Ti and these elements. C_α and C_β decrease linearly with the increase of these parameters. 收稿日期: 1983-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王孔探 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I3/118 1 #12 2 #12 3 The Science Technology and Application of Titanium, Eds.
