Abstract
The stirring assisted brazing of SiCp/A356 composites with a large size of diameter in air was investigated. A first stirring was applied in brazing of the composites at 470°C. Then, it was continuously heated up to 510°C. Then, a secondary stirring with a large size (2.4mm) diameter was introduced in process. It was found that a composite joint reinforced with SiC particles can be obtained by stirring at 510°C. The experiment result shows that micro-hardness of joint brazed by 2nd stirring is obviously higher than that of joint brazed without 2nd stirring. Moreover, micro-hardness of the upper part of joint is slightly higher than that of the bottom part.
