Abstract: To achieve the aim that reducing the brazing temperature of tungsten and CuCrZr alloy applied in the ITER equipment, Continuous and uniform amorphous ribbon with dimensional sizes of 10 mm in width and 80μm in thickness was prepared by melt-spinning a Cu47Ti33Zr11Ni8Si1 (at.%) alloy. The application of the amorphous foil as a new brazing filler for joint of tungsten and CuCrZr alloy have been investigated. The microstructures and mechanical properties of the joints obtained at different brazing temperatures were examined using optical microscopy, scanning electron microscopy, X-ray diffarction and microhardness indentation. Comparison of the microstructures and mechanical properties of the joints indicates that high quality interface bonding can be realized at an optimal barzing temperature of 900℃, and the joint zone thus formed is microcrack-free and the heat affected zone is fine-grained, exhibiting the highest microharness; the application of the amorphous foil as a new brazing filler can reduce the temperature for joint of tungsten and CuCrZr alloy effectively.
