“…But the stress form is different between brazing joints and practical applications. M. Salmaliyan [11] carried out shear strength and microhardness tests to investigate the mechanical properties of the joints and found that the presence of eutectic and dendritic solidification increased through Ti addition. Wu et al [12] designed a small 304 stainless steel/T2 red copper T-type brazed-joint specimen to study the brazing interface strength.…”

Brazing technology is widely used in modern industrial systems as an important connection method. The brazing joints are the weakest zone in the whole structure and directly determine the working efficiency and life of the entire system. However, the research on the connection mechanism and fracture behavior of brazing joints is still unclear. In this study, the peeling force and displacement curves during the peeling process are tested by using T-type specimens. Based on the cohesive zone model, the peeling energy of each part during the whole peeling process is calculated and analyzed. The results show that the whole peeling process can be divided into three stages, including the initial stage, crack propagation stage, and stable peeling stage. The peeling energy of each stage can be calculated experimentally. The larger the peeling energy, the better the joint performance. Then, a simplified calculation method for peeling energy is developed for T-type joints and is verified as accurate using experimental data. It is also observed that the increase in the base material thickness can effectively improve the peeling performance of the joints. This provides a feasible and effective method for peel strength calculation and evaluation in brazing joints.

“…They have reported that this type of interlayer can be used without partial melting of the additive powder particles, which is crucial to the properties of brazed single-crystal and polycrystalline alloys. Salmaliyan and Shamanian 33 investigated the effect of Ti powders on mechanical and metallurgical properties of IN718/BNi-2/316L diffusion couple. Their researches showed that the existence of eutectic phase, dendritic solidification and joint hardness increases by Ti addition.…”

The bonding strength, and microstructures of Cu and Al couples using metallic powders as interlayer during transient liquid phase bonding (TLP bonding) were investigated. The interfacial morphologies and microstructures were studied by scanning electron microscopy equipped with energy dispersive X-ray spectroscopy, and X-ray diffraction. First, to explore the optimum bonding time and temperature, nine samples were bonded without interlayers in a vacuum condition. Mechanical test results indicated that bonding at 560°C in 20 min returns the highest bond strength (84% of Al). This bonding condition was used to join ten samples with powder interlayers. Powders were prepared by mixing different combinations of Cu, Al (+Fe nanoparticles) and Zn. In the bonding zone, different Cu9Al4, CuAl, and CuAl2 intermetallic co-precipitate. The strongest bonding is formed in the sample with the 70Al (+Fe)-30Cu powder interlayer. Powder interlayers present thinner and more uniform intermetallic layers at the joint interface.
