摘要：

We fabricated SiCp/2024 composite joints using friction stir welding (FSW) and then, measured its mechanical properties. Grain of the stir zone (SZ) with SIC particles was much refined than that of the SZ without SiC particles. As the SIC particles facilitated the grain refinement in the SZ by the pinning effect, the particle including region had a much smaller grain size than the SZ without SIC particles. The hardness of the SZ with SIC particles was higher than that of the SZ without SiC particles in case of O-tempering samples. However, there was some difference between 0-tempering samples and T6 heat treatment sample which were hardness distribution of the weld were W-shape due to precipitates behavior during FSW.
