摘要(Abstract):

随着我国核电新能源的发展,新型材料的需求也在不断的增加,铜/不锈钢加筋板是其中一种,具有重要工程应用价值,目前无法用常规的冷、热加工工艺进行生产。通过爆炸焊接法,采用一种新的"凸台式"装药形式,在支撑模板设计及其填充方案、工装等方面进行了深入研究,优化了焊接参数,并对成品的结合界面进行了剪切强度测试、金相观测、电镜扫描和显微硬度测试。检测结果表明:铜/不锈钢焊接结合面为波状冶金结合界面,在波峰两侧存在含金属氧化物的"冠状"漩涡,结合界面附近的晶粒被拉长变细,显微硬度显著升高,界面结合强度超过铜材。
With the development of nuclear power in China,the demand for new materials was also increasing.The copper /stainless steel plate was also a new material.It had important engineering application value.But it was unable to use conventional cold,hot processing technology for production.Taking the copper alloy panel and 316 L stainless steel plate as a test material,a new " convex table " charge form was applied.Studies on the supporting template design and its filling scheme,the tool and the like were conducted,the welding parameters were optimized,the shear strength test,metallographic observation,electron microscopy and micro-hardness test were conducted in the interface.The test results showed that the copper/stainless steel weld joint surface was wave-like metallurgical bonding interface,that both sides of the peak presented a metal-oxide-containing " crown " vortex,and that the grain in the vicinity of the bonding interface was elongated tapered,micro-hardness was greatly enlarged,and the interface bonding strength was significantly elevated above that of the copper material.
