摘　　要：低活化铁素体/马氏体钢作为核聚变反应堆第一壁/包层首选的结构材料,在世界范围内得到了足够重视。中国也在国外研究的基础上,开发了具有自主知识产权的CLAM钢,开展了硅对材料性能影响的研究。利用光学显微镜和扫描电镜研究了加硅CLAM钢中的非金属夹杂物。结果表明:加硅CLAM钢的力学性能得到进一步改善,加硅导致非金属夹杂物的产生,弥散分布的方形、球形或三角形夹杂物属于硅酸盐型,尺寸5~10μm,呈灰色或黑色;加硅CLAM钢中的非金属硅夹杂物使材料的塑性和韧性降低。Low-activated ferritic/martensitic steel which is the preferred structural material of the nuclear fusion reactors has received sufficient attention in the world. On the basis of foreign research, China has developed CLAM steel with independent intellectual property rights. The research on the influence of silicon on the material properties was carried out.The non-metallic inclusions in the CLAM steel were analyzed by optical microscopy and scanning electron microscopy. The results show that the mechanical properties of the CLAM steel added silicon improves, and the addition of silicon leads to the formation of non-metallic inclusions. The square, sphere or triangle inclusions dispersed in CLAM steel are silicate type,which is in grey or black, the size is in 5-10 μm. The non-metallic inclusions in silicon added CLAM steel reduces the plasticity and toughness of the material.
