“…Yan et al 15 and Zhao et al 16 have succeeded in the vibration brazing of Al-MMCs in air by applying vibration to remove the oxide films on the composites. In the recent years, the semisolid joining technology has apparent advantage on joint with the absence of dendritic structure and shrinkage porosity 17 17,18…”

The semisolid brazing process of SiCp/A356 composites was investigated. The effects of temperature on the microstructure of the filler metal and the joints are discussed in this paper. The research results show that with increasing temperature, the solid fraction of the filler metal decreases. Moreover, the SiCp/A356 composites can be effectively joined with the semisolid filler metal by optimising the stirring temperature. It can be found that most of the oxide film on the surface of the composites is disrupted by mechanical stirring. In this case, the metallurgical bonds formed at the interface between the filler metal and the base materials. Since the semisolid temperature range of the filler metal is narrow, the accurate controlling of the weld pool temperature must be considered.

“…A mechanical stirring will be used to disrupt and remove the oxide film on the surface of the materials. Otherwise, the semi-solid joining technology has apparent advantage on joint with absence of dendritic structure and shrinkage porosity [9][10][11]. So, Semi-solid characters of joint were also discussed in papers.…”

The semi-solid brazing process of SiCp/A356 composites and 2024 aluminum alloy using Zn-Al eutectic filler metal at 450 °C has been investigated. The two substrates and Zn-Al filler metal were heated up to the semisolid temperature range of Zn-Al filler metal by a resistance heating plate. In order to mix the filler metal with the base metal of both sides to be a single uniform joint, a stirrer was introduced into the weld seam. After stirring, specimens were sectioned for analysis of macro- and micro-structures along the weld region. The research shows that SiCp/A356 composites and aluminum can be joining by semisolid metal. It can be found that almost half of the oxide film on the surface of the base metal was disrupted and removed through the observation by SEM. The metallurgical bonds formed between the filler metal and the base materials on the interface of oxide had been disrupted. Moreover, the oxide film of surface of aluminum alloy was more thoroughly disrupted and removed than that of surface of composites with existing of SiC particle.

The semi-solid brazing process of SiCp/A356 composites and aluminum alloy was investigated. The two substrates were heated up to the semisolid temperature range of Zn-Al filler metal in the joint region by a resistance heating plate. At this point a stirrer was introduced into the weld seam in order to mix filler metal and the two sides of substrates into a single uniform joint. After stirring, specimens were sectioned for analysis of macro- and micro-structures along the weld region. The research shows that SiCp/A356 composites and aluminum can be successfully joining with semi-solid filler metal. It can be found that most of the oxide film on the surface of the base metal was disrupted and removed through the observation by SEM. The metallurgical bonds formed between the filler metal and the base materials. Moreover, the oxide film of surface of aluminum alloy was more thoroughly disrupted and removed than that of surface of composites with existing of Sic particle. The joint microstructure with globular α-Al grain enclosed by rich-Zn phase can be obtained after stirring brazing.
