| 摘 要： | 本文利用扫描电子显微镜对控轧14MnNbRE钢非金属夹杂物进行了观察,并利用能谱仪分析了非金属夹杂物的化学成分。含有0.054%RE的14MnNbRE钢中的硫化物主要是细小球状的稀土元素硫化物RE_2S_3,尚存的少量条状MnS型夹杂物也变得小而短。

| Abstract: | Non-metallic inclusions in the steel 14MnNbRE control-rolled were studied using a scanning electron microscopy (SEM), of which, the chemical composition were analyzed by EDS. Most of sulphides in the steel added 0.054%RE were fine and spherical RE_2S_3,and the size of remaining MnS was shorter and smaller than that in the steel non-RE added. |
