提高成材率和复合界面质量是制备多层复合板的难题.本工作提出一种多层复合板的高成材率热轧制备方法,即采用氩弧焊固定各层原料板组成坯料,坯料放入金属套后抽真空,再加热到1000~1200℃进行多道次轧制,成功制备出2.5mm厚的67层复合板.通过金相显微镜及电子显微镜观察和分析了界面组织及元素扩散行为,采用拉伸、剪切实验测定复合板的力学性能,并分析其剪切断口.结果表明:采用两步组坯复合和工艺优化,多层复合板的轧制成材率达90%以上.多层复合板具有良好的结合界面,其抗剪强度达到241MPa.9Cr18和1Cr17镍中间层可以较为有效地阻碍界面附近的碳扩散并改善复合板的组织特征.
For multi-layer plate ,it is a difficult problem to increase product yield rate and improve bonding interface quality .A high yield hot-rolled method of multilayered plate was proposed .The raw strips and plate were fixed by argon arc welding .The combined billet was put into a metal box and vacuum pumped ,and then heated and rolled by multi passes at the temperature of 1000-1200℃ .The 67 layered plate with the thickness of 2 .5mm was successfully produced .The interfacial microstruc-tures and diffusion behavior were investigated and analyzed by optical microscopy and scan electronic microscopy .The tensile and shear strength were tested ,and the shear fractures were analyzed .The results show that the multilayered plate yield rate is more than 90% by two steps billet combination method and rolling process optimization .The good bonding interface quality is obtained ,the shear strength of multilayered plate reaches 241MPa .Nickel interlayer between 9Cr18 and 1Cr17 can not only prevent the diffusion of carbon ,but also improve the microstructure characteristics .
