Ultrasonic-promoted rapid transient liquid phase bonding of high volume fraction SiC particle reinforced aluminum-based metal matrix composite in low temperature

Sonoprocessing of wetting of SiC by liquid Al: A thermodynamic and kinetic study

“…The effect of acoustic cavitation is crucial for the interfacial reaction between Al and SiC. After propagating 20 kHz ultrasonic waves into the melt, micro-jets are generated by the ultrasonics, and the cavitation bubbles collapse, hit, and broke in molten Al [40] . Since there are instantaneous high temperature and high pressure inside the melt, very strong temperature shock and thermal stress shock are given to the oxide film.…”

Contemporary Progresses in Ultrasonic Welding of Aluminum Metal Matrix Composites

“…Hence, keeping all the parameters into count, in this way, it would obtain the final product, which is welded workpieces of Aluminum by using ultrasonic welding. However, this is applicable for some cases of Aluminum thicknesses, which will range up to less than or equal to 1 mm, because if we try to operate the system with a harder workpiece with similar thickness as in a pure Aluminum case, then it will eventually fail to complete the process of welding, or may damage the ultrasonic welding machine in some cases, especially the tip (Ma et al, 2020). Table 3 is shown in the ultrasonic vibration time(s) v/s shear strength (MPa).…”

Research Progress on Aluminum-based Composites and Applications

“…Some foreign researchers [5] also applied ultrasonic wave technology to strengthen binding between SiC particles and Al base to further increase volume fraction of SiC particles. At present [6], SiCp/Al is used to skin of airplane in addition to engine piston and brake disc in the automobile field. Due to the low expansion rate and good shaping performance, SiCp/Al is also extensively applied to tube of satellite T/R component or high-power carrier structure [7].…”
