借助光学显微镜、扫描电镜和电子探针 ,分析了反向凝固轧制后的不锈钢带的熔合区及碳的扩散 ,并研究了铬元素和铁元素沿横截面的分布情况。试验结果表明 ,母带和凝固层靠相互扩散形成固溶体而实现良好的冶金结合。 With the aid of optical microscope, scanning electron microscope and electron probe, the fusion zone and carbon diffusion of stainless steel strip after reverse solidification and rolling were analyzed. The distribution of chromium and iron along the cross section was also studied. The experimental results show that the masterbatch and the solidified layer form a solid solution by interdiffusion to achieve good metallurgical bonding.
