Microstructure and mechanical properties of diffusion bonded Al/Mg2Si metal matrix in situ composite

Role of Mg2Si particles on mechanical, wear, and corrosion behaviors of friction stir welding of AA6061-T6 and Al-Mg2Si composite

“…Al-Mg 2 Si composite is typically in-situ produced by adding Mg and Si to aluminum melt in excess of their solubility limits. [1][2][3][4][5][6] In the hypereutectic condition, the Mg 2 Si phase (akin to a ceramic reinforcement) precipitates into the aluminum matrix in two forms which are primary particles and secondary flake-like networks, respectively. These precipitates create suitable properties such as high melting temperature (1085 C), low density (1.99 Â 10 3 kg m À3 ), high hardness (4500 MN m À2 ), low thermal expansion coefficient (7.5 Â 10 À6 K À1 ), and high elastic modulus.…”

Study on the micro-interface behavior of 2024Al light alloy bonded by ultrasonic assisted solid phase diffusion welding with Ag interlayer under atmosphere

“…Traditional solid phase diffusion welding technology can reduce the formation of joint defects such as deformation, cracking and segregation [10,11]. This process relies on the application of high pressures for long times to promote microplastic deformation of the surface of the material to be welded, and elemental forms a close joining.…”

Evaluation of Microstructure and Mechanical Properties in Dissimilar Joint of SSM7075 with SSM356 Aluminum Alloy using Diffusion Bonding

“…Solidstate-welding techniques are interesting as researchers have recently found these new techniques appropriate for welding different materials. Typically, there also have many successful methods, such as friction stir welding [6], friction welding [7], and diffusion bonding [8][9][10]. Among these welding techniques, the diffusion bonding technique is interesting because it has been widely used to produce reliable interfaces between similar and dissimilar materials.…”
