Abstract: Graphite has been widely used in nuclear industry.Joining of graphite and copper can improve neat conduction of structure, so bonding of these two materials is a key technology needed to be solved.Copper and high-strength graphite were brazed with amorphous TiZrNiCu filler metal in vacuum circumstance, and the effect of parameters on the interface was studied.The results show that fracture occurred in graphite during tensile and shear strength test.According to the microstructure analysis, thin TiC layer generated due to the reaction of filler metal and graphite, which formed high-strength interface.Brazing seam was mainly consisted of solid solution, with intermetalic compound distributing in it.
