Diffusion bonding of AA7075/AZ80 joint has been synthesized, studied and demonstrated to optimize the lap shear, Ram tensile and hardness properties. Response surface methodology (RSM) is applied to develop mathematical relationships between the control parameters of two factors and three-level responses. Optimization experiments were carried out to check the models’ adequacy. The results show a high degree of coincidence between the optimized and actual values, implying that the proposed models can accurately forecast lap shear, Ram tensile, and hardness properties force within the process parameter constraints of the diffusion bonding process. Scanned electron microscopic Scanning Electron Microscope (SEM) images, optical images, and radiography film photography investigations also revealed the excellent fracture resistance of the AA7075/AZ80 alloy, making it a suitable material for deployment in engineering applications.

The size and distribution of the silicon phase and intermetallic phase are important factors affecting the properties of Al11Si3Cu2NiMg alloy (M142). In this study, BNNS and micro-TiB2 were used to synergistically refine and reinforce M142 composites (M142-BNNS-TiB2). After T6 heat treatment, the comprehensive mechanical properties of M142-BN-TiB2 composites were excellent, with an ultimate tensile strength of 463 MPa and an elongation of 2.6%. In addition, the introduction of BNNS and micro-TiB2 changed the fracture mode of M142 from brittle fracture to quasi-cleavage fracture, and the introduction of BNNS and micro-TiB2 refined the Si phase and intermetallic phase, which could change the origin of the crack in the composite, thus improving the ductility of the composite.
