【摘要】 用电解分离、化学分析、电子探针微区分析和晶格常数精密测量等方法,研究了钢铁中混合稀土的存在行为,结果表明:通常稀土钢中的固溶稀土量可达0.02wt%左右,纯铁中接近0.08wt%;在所研究的纯铁中,除生成稀土夹杂物和一定固溶量外,过量稀土形成富 Ce 的 RE₂Fe₁₇相富 Ce 的 REFe₂相、和富 La 的稀土金属相。更多还原

【Abstract】 The existent behavior of mixed rare earth in Iron and steel was studied by means of electro-lytic separation-chemical analysis,EPMA,and accurate measurement of lattice parameter.The resultsshow that the solubility of mixed rare earths can reach 0.02wt% in commercial steels,and 0.08wt%in pure iron.Besides rare earth inclusions,there are two kinds of Ce-rich compounds,RE₂Fe₁₇andREFe₂,and one kind of La-rich metallic phase in investigated iron.更多还原
