“…EDS analysis indicated by point D confirms the presence of Ti, Zr and Sn in the rod-like phase. The at.% of the elements indicates that this phase is identical to (Zr, Ti)5Sn3 phase composition in the literature, as shown in Table 2 [30,31]. Elemental mapping of the magnified microstructure as shown in Figure 3c-g confirms the coexistence of Zr, Ti and Sn in (Zr, Ti)5Sn3 phase.…”

“…Elemental mapping of the magnified microstructure as shown in Figure 3c-g confirms the coexistence of Zr, Ti and Sn in (Zr, Ti)5Sn3 phase. Nowotny et al reported that Zr5Sn3 and Ti5Sn3 IMCs can substitute Ti and Zr atoms to form a hexagonal (Zr, Ti)5Sn3 phase [31]. Several other researchers also support the formation of (Zr, Ti)5Sn3 phase in the Sn-Zr-Ti system over a wide range of Ti and Zr compositions [31][32][33].…”

“…Nowotny et al reported that Zr 5 Sn 3 and Ti 5 Sn 3 IMCs can substitute Ti and Zr atoms to form a hexagonal (Zr, Ti) 5 Sn 3 phase [31]. Several other researchers also support the formation of (Zr, Ti) 5 Sn 3 phase in the Sn-Zr-Ti system over a wide range of Ti and Zr compositions [31][32][33]. Fine (Zr, Ti) 5 Sn 3 phase formed upon the addition of Ti and Sn in Ag-Cu-Zr filler could be more beneficial in mechanical properties as compared to the blocky Cu 4 AgZr IMC in Ag-Cu-Zr and Ag-Cu-Zr-Ti fillers [22,34].…”

The study was designed to investigate the synergic effect of Ti and Sn in the active metal brazing of Al2O3 ceramic to copper brazed, using the multicomponent Ag-Cu-Zr filler alloy. Numerous fine and hexagonal-shaped rod-like ternary intermetallic (Zr, Ti)5Sn3 phase (L/D = 5.1 ± 0.8, measured in microns) were found dispersed in the Ag-Cu matrix of Ag-18Cu-6Sn-3Zr-1Ti alloy, along with the ternary CuZrSn intermetallic phases. An approximate 15° reduction in contact angle and 3.1 °C reduction in melting point are observed upon the incorporation of Ti and Sn in Ag-18Cu-3Zr filler. Interestingly, the interface microstructure of Al2O3/Cu joints brazed by using Ag-18Cu-6Sn-3Zr-1Ti filler shows a double reaction layer: a discontinuous Ti-rich layer consisting of (Cu, Al)3(Ti, Zr)3O, TiO, and in-situ Cu-(Ti, Zr) precipitates on the Al2O3 side and continuous Zr-rich layer consisting of ZrO2 on the filler side. The shear strength achieved in Al2O3/Cu joints brazed with Ag-18Cu-6Sn-3Zr-1Ti filler is 31% higher, compared to the joints brazed with Ag-18Cu-6Sn-3Zr filler. Failure analysis reveals a composite fracture mode indicating a strong interface bonding in Al2O3/Ag-18Cu-6Sn-3Zr-1Ti filler/Cu joints. The findings will be helpful towards the development of high entropy brazing fillers in the future.
