摘要(Abstract)：

为制取适用于超导托卡马克核聚变装置中的具有中空结构的316L/CuCrZr复合材料，在不锈钢基板预制微孔后再进行316L/CuCrZr的爆炸复合，然后对微孔进行扩孔，获得了在316L/CuCrZr界面处具有换热通道的316L/CuCrZr爆炸复合板。通过超声检测、微观结构观察、机械测试和核泄漏实验等手段研究了316L/CuCrZr复合界面的结合状态、显微组织、EDS能谱线扫描分析、换热通道的耐压及密封。结果表明，具有微孔结构的316L/CuCrZr爆炸复合板焊接质量良好，以均匀的波形结合，没有空隙和裂纹等缺陷，换热通道具有较好的密封性、耐高温高压性，能够满足托卡马克核聚变装置使用的要求。
In order to prepare the 316L/CuCrZr composite with hollow structure suitable for the superconducting Tokamak nuclear fusion device, the 316L/CuCrZr explosive composite was carried out after the microholes were prefabricated on the stainless steel substrate, then, the 316L/CuCrZr explosive composite plate with heat transfer channel at the interface of 316L/CuCrZr was obtained by expanding the micropores.The bonding state, microstructure, EDS scanning analysis, pressure resistance and sealing of heat transfer channel of 316L/CuCrZr composite interface were studied by means of ultrasonic inspection, microstructure observation, mechanical testing and nuclear leakage experiment. The results show that the 316L/CuCrZr explosive composite plate with microporous structure has good welding quality, uniform waveform bonding, no voids, cracks and other defects, and the heat transfer channel has good sealing performance, high temperature and high pressure resistance, which can meet the requirements of tokmak fusion device.
