摘　　要：以CuCrZr合金板为基板,316L(N)-IG不锈钢板为复板,制作了CuCrZr/316L(N)-IG爆炸复合板用于ITER第一壁热沉部件。对其进行了金相试验、硬度测试以及拉伸试验等。结果显示,复合板界面层具有明显的波状组织,平均波长和波高分别为1200mm和500mm,室温下抗拉强度达到394MPa。用复合板制作了6个第一壁小模块,进行质量认证试验,结果表明其满足ITER要求。CuCrZr/316L（N）-IG explosion bi-metallic plate manufactured by CuCrZr plate and 316L（N）-IG plate was used as heat sink component of ITER first wall（FW）. CuCrZr plate and 316L（N）-IG plate were used as base plate and flyer plate, respectively. Metallographic test, hardness test and tensile test were performed. It turns out that there is an obvious wavy microstructure on the interface of CuCrZr/316L（N）-IG with mean wave length of 1200μm and mean wave height of 500μm. The tensile strength is up to 394 MPa at room temperature. Six FW mockups were made, and it turned out that the bi-metallic plate met ITER requirement.
