【摘要】 利用SEM电镜、能谱分析仪、以及等离子光谱分析仪,对稀土镧在纯净钢中的固溶规律及夹杂物的转变规律进行了研究。结果表明,当稀土镧加入量在0％～0．1％之间时,随着加入量的增加,La的固溶量由0％增加到0．0226％,夹杂物中的La含量有由0％增加到0．02％,夹杂物的种类和形状却发生了明显的变化。随着La含量的增加,夹杂物由硅酸盐、铝酸盐转变为稀土La的氧化物、硫氧化物。而且夹杂物形状也由不规则的形状,转变为规则的球形。更多还原

【Abstract】 By SEM, EDS and ICP spectral analysis, the solution law of La and the transformation law of inclusions are investigated in present work. The results show that the La solution content and the La content in inclusions increase from 0% to 0.0226% and from 0% to 0.02%, respectively, with the adding La content between 0% and 0.1% in steel. The kind of inclusions makes transformation obviously from silicate and aluminate into LaAlO3, LaS, and La2O2S, LaxS, and that the inclusions change from irregular shape into regular sphericity.更多还原
