: The joining of AZ31B Mg alloy to 6061 Al alloy was investigated at different joining temperatures by vacuum diffusion bonding method. The microstructures of Mg/Al dissimilar joints were studied by means..., and the corresponding joint exhibits brittle fracture at the intermetallic compound layer of Mg17Al12. Key words: vacuum diffusion bonding; 6061 aluminum alloy; AZ31 magnesium alloy; dissimilar metal joint......
condition, and is unfavorable to the diffusion between the Au and Ag metal, which leads to lower strength or unsuccessful bonding. The bonding process between Au and Ag is an atom combination process, which... bonding or low bonding strength. 2) Appropriate temperature can soften the metal material, and accelerate the diffusion between the Au and Ag atom, which results in good bonding. According to atom......
, the fabricated samples were thermally treated in a high vacuum environment pumped by a 300 l/s diffusion pump. The coatings were isothermally heat-treated for 1 h at different temperatures, i.e. 100, 200, 340...

Trans. Nonferrous Met. Soc. China 25(2015) 80-87 Bonding interface characteristic and shear strength of diffusion bonded Ti-17 titanium alloy Hong LI, Chao ZHANG, Hong-bin LIU, Miao-quan LI School... and shear strength of diffusion bonded Ti-17 titanium alloy at different bonding time were investigated. The results show that the average size of voids decreases while the amount of voids decreases after......
a copper interlayer was investigated in a vacuum free diffusion bonding process. The diffusion bonding was carried out at temperatures of 820, 850 and 870 °C for 50, 70 and 90 min, respectively under 1...Trans. Nonferrous Met. Soc.
