“…In high-temperature brazing, the liquid phase temperature of the metal filler must be higher than 900 • C without solder. Many researches on braze diffusion bonding have been carried out [7][8][9]. It is difficult to prevent * Corresponding author.…”

“…The metal filler, BNi-3, was selected to guarantee a lower melting temperature than the substrate materials, nickel cylinders and SUS-316 stainless steel. The general gap [3,8] for vacuum diffusion bonding was selected as 0.05 mm. At a temperature between the melting points of the metal filler and substrate materials, diffusion and bonding of the substrate materials are accomplished through penetration and capillarity of the melting filler.…”

“…In addition, it is expected that the decrease in brazing temperature can reduce the residual stress developed in the joint and hence increase the joint strength [1][2][3] . Since the first amorphous filler alloy patent was applied by D'Silva in 1979, amorphous filler alloys have attracted increasing attention in the fields of ceramic/ceramic [4,5] , metal/metal [6][7][8] and ceramic/ metal [9][10][11][12] joining owing to their unique properties, instead of crystalline alloy fillers.…”

Amorphous Ti-Cu-Zr-Ni fi ller foils with low melting point of 1 133 K were synthesized using a melt-spinning method in argon atmosphere. A Ti 2 AlNb based alloy was brazed at 1 153-1 223 K for 600-3 000 s. The effects of brazing temperature (T b ) and time (t b ) on the shear strength of the joints were investigated. The results showed that the joint strength was signifi cantly affected by the reaction layer thickness. The optimum brazing parameters can be determined as follows: T b =1 173 K, and t b =600 s. The maximum tensile strength of the joint obtained can reach 260 MPa. Furthermore, the activation energy Q and the growth velocity A 0 of the reaction layer in the brazed joints were calculated to be 161.742 kJ/mol and 0.213 m 2 /s, respectively. The growth of the reaction layer (y) could be expressed by the expression: y 2 =0.213exp(−19 454/T b )t b .

“…Consequently, instead of crystalline alloy fillers, amorphous active alloy has attracted increased attention in the fields of ceramic/ceramic and ceramic/metal joining owing to its unique properties [21]. Amorphous alloy, a material at unsteady state, can accelerate atomic diffusion and surface reaction during high temperature brazing process [22][23][24][25]. In addition, it is expected to decrease brazing temperature so as to reduce residual stress developed in the joint and hence to increase the joint strength.…”
