摘要：

The surfaces of cast hypereutectic Al-Si-Cu-Ni-La alloy plate was subjected to single pass Friction Stir Processing (FSP) with the aim of decreasing the Si and intermetallic particles size, porosity, and enhancing tensile properties. After FSP, the FS-processed sample shows an improvement in tensile strength value of about 27.5% compared to the as cast base alloy. Optical and scanning electron micrographs indicated that FSP significantly decreases the size of Si, intermetallic particles, and reduced porosity in the alloy, which contributed to the enhancement in tensile properties.
