摘　　要：分析了由反向凝固工艺得到的复合不锈钢带的组成情况，以及钢带中元素的偏析，并对不锈钢凝固层的实际晶粒度进行了测定．研究结果表明：不锈钢凝固层组织为铁素体和碳化物；母带组织为铁素体和马氏体;过渡区为铁素体和珠光体，过渡区的宽度为50μm．不锈钢凝固层的实际晶粒度为5．8～6．3．The metallographic structure, the elements segregation and the grain size number of the composite stainless steel strip were discussed.Based on the results the conclusions were follow:the metallographic structure of composite stainless steel strip is ferrite and carbide,the structure of mother strip is ferrite and martensite,and the structure of the transition region is ferrite and pearlite.The width of the transition region is about 50 μn; the factor grain size of stainless layer is between 5.8 and 6.3.

关 键 词：反向凝固 复合不锈钢带 实际晶粒度
