摘      要：Microstructure and mechanical properties of SiCp /AA5083 composite fabricated by friction stir welding (FSW) were *** influence of the number of FSW passes on the distribution of SiC particles and mechanical properties in the joint was *** one pass,the SiC particles were entangled in the upper side of the stir zone (SZ).However,the particle distribution became more uniform after two passes due to the repeated stirring of the *** the SiC particles facilitate the grain refinement in the SZ by the pinning effect,the particle including region has much smaller grain size than the SZ without SiC *** SiCp /AA5083 composite region exhibits a Vickers hardness of HV90,which is much higher than the value of HV80 in the SZ produced by FSW without SiC particles.
