Brazing of Mo and Nb using two active braze alloys

Infrared brazing of Ti50Ni50 shape memory alloy using two Ag–Cu–Ti active braze alloys

“…Consequently, it is expected that the molten braze tends to be separated into two liquids during brazing. One is rich in Ag, and the other liquid is rich in both Cu and Ti [14,18]. According to Fig.…”

Infrared brazing of Ti–6Al–4V using two silver-based braze alloys

“…Quantitative chemical analysis was performed using a JEOL JXA-8600SX electron probe microanalyzer (EPMA) with an operation voltage of 20 kV and minimum spot size of 1 m. The shear test was performed using a Shimadzu AG-10 universal testing machine with a constant crosshead speed of 0.5 mm/min to compress the brazed specimen (Shiue et al, 2003Chuang et al, 2005) difference in order to verify the reproduction of shear test data. Failure analysis of the brazed specimen after the shear test was accomplished using the Hitachi 3500H SEM.…”

“…Infrared brazing is a novel process characterized with a high heating rate up to 3000 • C/min (Shiue et al, 2003Chuang et al, 2005). Accordingly, it is expected that both erosion of the substrate and excessive growth of intermetallic phase in the brazed joint are significantly decreased.…”

Control of residual stresses in 2Si-B-3C-N and Nb joints by the Ag-Cu-Ti + Mo composite interlayer

“…Therefore, it is necessary to perform effective joining of Si-B-C-N with other ceramics or metals, such as Nb. Such methods are suited for components required to operate as a high-temperature, for a prolonged period of time [12,13].…”
