Exploring the effects of SiC reinforcement incorporation on mechanical properties of friction stir welded 7075 aluminum alloy: Fatigue life, impact energy, tensile strength

Investigation on AA5083/AA7075+Al2O3 Joint Fabricated by Friction Stir Welding: Characterizing Microstructure, Corrosion and Toughness Behavior

“…As a matter of fact, loose bonding of reinforcements with the substrate and probable clusters aggregation reduced the required fracture energy. This result is against Bahrami et al 13 achievements in the case of AA7075 joint reinforced with SiC nanoparticles. As it is addressed, the reason why they found higher fracture toughness for SiC-included specimen was the excellent bonding between reinforcements and the matrix.…”

“…More recently, based on a novel approach, Bahrami et al 13 applied FSW for joining of two AA7075 plates using SiC reinforcements along the joint line and found promising results from the standpoint of impact toughness. They reported that excellent bonding between reinforcements and the substrate was the reason of positive effect of SiC particles on impact energy absorption.…”

Microstructure and Mechanical Properties of 45 vol.% SiCp/7075Al Composite

“…Several methods, such as stir casting technique [10e13] , powder metallurgy [14e16] spraying process [17,18] , friction stir welding [19,20] and squeeze casting [21] , have been used to prepare SiC p /7xxxAl composites. Rajamuthamilselvan et al [10,11] investigated the hot deformation behavior of 15 and 20 vol.% SiC p /7075Al composites prepared by stir casting, and found that the composites demonstrated higher flow stress, efficiency and lower instability regimes than 7075 alloy.…”

“…Sheu et al [15] found that the hot-pressed 20 vol.% SiC p /7075Al composite showed significant improvement on the wear resistance properties. Bahrami et al [19,20] found that the tensile strength, ductility, fatigue life and toughness of SiC p /7075Al composites were increased due to the presence of nano SiC particles. Pandey et al [22] found that 15 vol.% SiC p /7093Al composite demonstrated improved tensile strength and very attractive fracture strain (more than 6%).…”

Microstructures and Compressive Properties of Al Matrix Composites Reinforced with Bimodal Hybrid In-Situ Nano-/Micro-Sized TiC Particles

“…Researchers have demonstrated that composites that were reinforced by nano-sized particle possess better properties, such as higher strength, higher hardness, outstanding ductility, and fracture toughness [18,20]. However, nano-particles might cause poor interface bonding and non-homogeneous dispersion, which has seriously hampered the strengthening effect, and affected the properties of the composites [21,22,23]. Also, more research work must be carried out to solve the problem of agglomeration of nano-particles dispersion.…”
