摘要/Abstract

摘要： 为实现面向等离子体材料钨(W)和热沉材料铜铬镐(CuCrZr)合金的可靠连接，对纯铁(Fe)作为W/CuCrZr合金热等静压连接中间层的可行性进行了探索性研究。在850℃/150MPa/135min的热等静压参数下制作了W/Fe/CuCrZr合金的实验模块，分别对连接界面进行了焊接界面、微观形貌、组织成分及剪切力学性能的检测分析。检测结果显示，两连接界面无明显缺陷，均发生了约0.5μm的短距离互扩散，且均未生成明显的反应相，连接界面呈现出较好的塑性，剪切强度大于186.5MPa。因此，纯铁作为中间层实现了W/CuCrZr合金的可靠连接。用ANSYS Workbench平台对模块进行的高热负荷下的瞬态传热模拟表明W/Fe/CuCrZr合金模块最高可承受16MW·m^-2的热负荷。

Abstract: In order to achieve reliable connection of plasma-facing material tungsten and heat sink material CuCrZr alloy, the feasibility of using pure iron as the interlayer of W and CuCrZr alloy bonded by hot isostatic pressing (HIP) techinique was explored. An experimental module of W/Fe/CuCrZr alloy was fabricated under the hot isostatic pressure of 850℃/150MPa/135min, and the welding interface, the micro-morphology, the microstructure composition and the shear mechanical properties of the connection interface were measured and analyzed. The results show that there are no obvious defects on the two connection interfaces, and short-distance interdiffusion of about 0.5μm has occurred, and no obvious reaction phase has been formed. The connection interface shows good plasticity and the shear strength is greater than 186.5MPa. Thereby, pure Fe as an intermediate layer achieves a reliable connection of W/CuCrZr alloy. The module’s transient heat transfer under high heat flux simulated with ANSYS Workbench shows that the W/Fe/CuCrZr alloy module can withstand a maximum heat flux of 16MW·m^-2.
