    摘要:

    本文在真空热熔W/CuCrZr复合板的基础上进行了爆炸焊接,采用金相显微镜、扫描电镜分析(SEM)分析及能量色散X射线光谱(EDS)分析对结合界面进行微观形貌观察,同时结合有限元计算探索了热熔爆炸W/CuCrZr复合板界面的演化机制。研究结果表明:热熔爆炸焊接W/CuCrZr 复合板的界面结合良好,具有3~8μm交叉熔融区, 但W侧产生了裂纹;数值模拟再现了热熔爆炸焊接过程中结合界面压力、应力、应变、内能变化规律,实验产生裂纹的位置和数值模拟计算的高应力位置吻合,热熔爆炸焊接界面附近的高压、高温进一步促进了界面的结合。

    Abstract:

    In this paper, explosion welding is carried out on the basis of vacuum hot melt W/CuCrZr composite plate. Metallurgical microscopy, scanning electron microscopy (SEM) analysis and energy dispersive X-ray spectroscopy (EDS) analysis were used to observe the microscopic morphology of the bonding interface. At the same time, combined with finite element calculations, the evolution mechanism of the interface of the hot melt explosion W/CuCrZr composite plate was explored. The results show that the interface bonding of the hot-melt explosion welded W/CuCrZr composite plate is good,with 3~8μm cross-melting zone, but cracks developed on the W side; The numerical simulation reproduces the changes of combined interface pressure, stress, strain and internal energy in the process of hot melt explosion welding. The location of the crack generated by the experiment coincides with the high stress position calculated by numerical simulation.The high pressure and high temperature near the hot-melt explosion welding interface further promote the bonding of the interface.
