钨(W)钢与低活化铁素体-马氏体钢(RAFM)的有效连接是制造未来聚变堆偏滤器和第一壁的关键。在本工作中，低活性铁基非晶合金Fe67.8Cr11.5Si2.1B18.6(at.%)是用来钎焊W和RAFM钢的钎料。采用非晶态合金钎料与钒中间层金属在1270 °C进行短时真空钎焊，获得了无裂纹连接，接头中金属间化合物相和单一固溶体相交替形成层状组织，表现出软硬交替的力学特性。W原子通过FeW2B2和Fe3B相的形成阻止了W原子向钢基体的长距离扩散，而Si和B元素则局限在接头的主结合缝中。按照标准的热处理程序，实现了钢的组织回复。研究结果表明，用低活性铁基非晶态合金制备强韧的W/RAFM接头是一种很有前途的方法。
The effective joining of tungsten (W) and reduced activation ferritic-martensitic (RAFM) steels is crucial to fabrication of the divertors and first wall of future fusion reactors. In the present work, a low-activation Fe-based amorphous alloy of Fe67.8Cr11.5Si2.1B18.6(at. %) is designed as the filler metal for brazing W and RAFM steels. Crack-free joint has been achieved with the amorphous alloy filler and a vanadium interlayer metal by short-time vacuum brazing at 1270 °C. Layer structures composed of intermetallic phases and single solid-solution phases, respectively, are alternately formed in the W/RAFM steel joint, exhibiting alternating hard and soft mechanical characteristic. Long-distance diffusion of W atoms to the steel substrate is blocked by the formation of FeW2B2and Fe3B phases, and Si and B elements are confined within the main bonding seam of the joints. Microstructure recovery for the steel is realized following the standard heat treatment procedures. The present results suggest a promising way of making strong and tough W/RAFM joints with low-activation Fe-based amorphous alloys.
