TC4/TA18 titanium alloy honey-comb sandwich construction is brazed by amorphous foil solder Ti-37.5Zr-15Cu-15Ni (mass fraction). The effect of brazing temperature and holding time on the micro-structure of brazing interface and the tensile strength of TC4/TA18 titanium alloy honeycomb sandwich construc-tion is researched. The optimized brazing technology is 920℃/90min with 80μm solder in depth. With the opti-mized brazing technology, the average value of the tensile strength of specimens is 19.82MPa, and the honeycomb core is the weak part.
