Cu+TiB2 composite filler for brazing Al2O3 and Ti–6Al–4V alloy

Effects of brazing temperature on microstructure and mechanical performance of Al2O3/AgCuTi/Fe–Ni–Co brazed joints

“…M. Brochu [7] studied the active brazing of Si 3 N 4 ceramic and FA-129 alloy, and they found a reaction layer formed at Si 3 N 4 /Cu interface and discussed the relation between the thickness and brazing time. The Al 2 O 3 /Al 2 O 3 joint can be achieved using AgeCueTi þ B þ TiH 2 composite filler [8], the results show that the addition of B powders in composite filler increases TiB whiskers content, but decreases the thickness of Ti 3 (Cu,Al) 3 O layer, while the higher TiH 2 powders content thickens Ti 3 (Cu,Al) 3 …”

Joining Alumina to Titanium Alloys Using Ag-Cu Sputter-Coated Ti Brazing Filler

“…A maximum shear strength was obtained for the joint processed at 850 • C for 40 min. Wu et al [22] The brazing of an Al 2 O 3 to Ti6Al4V alloy was also reported using filler alloys composed of TiB 2 additive ball milled with Cu-Ti powder [23], the same additive milled with Cu powder [24], a commercial Ag-Cu-Ti powder mixed with B powder [25], and Ag-Cu eutectic powders mixed with different contents of B [3]. The common aspect of these studies involved the use of B for in situ formation of TiB whiskers in order to minimize the CTE between the base materials.…”

Microstructural optimization of active element and reinforcement proportion of Si3N4/42CrMo joints

“…Then some of the residual stress between the filler material and the substrates can be relieved [4]. The interaction between reinforcements and Ti also attracted extensive attention in these years [5]. One of the most common reinforcing materials is SiC particle [6].…”
