“…Brazing is used to join composite and ceramic materials also. In the latest developments pertaining to ultra-light-weight composite structures, carbon fibre reinforced Al matrix (C f /Al) was joined to TC4 alloy by Shen et al 24 using Ag-Cu filler with Ni-Al-Zr interlayer. Ceramic materials like YIG were used in high technology areas of microwave systems like radars, telecommunication and RF systems.…”

In the present investigation, a dissimilar metal joint between Titanium alloy (Ti6Al4V, ELI) and pure Aluminium (Al) was achieved using an Al-Si based filler alloy by vacuum brazing technique. A sound dissimilar joint of Ti to Al was achieved after a series of pilot experiments with overlap configuration. A thin foil of 0.2 mm thick Al-Si was used as filler alloy. With an overlap of 7.5 mm, the average joint strength achieved was 64 MPa. Mechanical properties were evaluated by varying the overlaps of the vacuum brazed joints and then compared. The average joint strength achieved for an overlap distance of 3, 6 and 9 mm were 57 ± 0.5, 53 ± 0.5 and 59 ± 0.5 MPa, respectively. The brazed joints were investigated for macrostructure, microstructure, scanning electron microscope and electron probe micro analyser analysis for characterization studies.

“…The large difference in both thermal and physical properties of Al and steel is one of the critical issues during dissimilar joining. [1][2][3] In addition, negligible solubility between Al and Fe leads to the formation of a hard and brittle Fe-Al intermetallic layer at the interface of deposited filler and steel. 4,5 Excessive formation of these intermetallic phases can deteriorate the strength of the joints due to correspondingly increased brittleness of the interfacial region.…”

The aim of this work is to optimize the process parameters and to analyze the evolution of mechanical and microstructural properties during CMT spot weld-brazing of dissimilar materials aluminium-steel. In doing so, process parameters including hold time, hole diameter and pre-setting gap were optimized using Taguchi orthogonal design and then the microstructure of the interfacial region was characterized using optical microscopy, scanning electron microscopy and X-ray diffraction. Shear-tensile testing was performed to evaluate the load-bearing capacity of the joints. It was observed that the strength of spot weld-brazed joints is primarily dependent on the interfacial area and intermetallic compounds at the interface. High hold time and wider hole diameter resulted in poor joint strength due to excessive intermetallic formation and an unfilled region in the joint. In addition, Cyclogram revealed that the joining process was comparatively unstable for the wider hole and high hold time due to the formation of zinc fumes. The provision of a pre-setting gap in between the sheets showed a positive impact on the joint strength.
