The microstructures of inertia-friction welds (IFRWs) on an aluminum metal matrix composite have been investigated using several ultrasonic examination (UE) techniques as well as standard characterization methods. This study represents one of the first efforts to utilize UE methods for microstructural characterization of welds. The flow line patterns and dimensions of the different weld zones in IFR welds on a SiC-reinforced 8009 aluminum composite (8009/SiC/11p) have been determined using optical microscopy (OM) and scanning-electron microscopy (SEM) as well as the following UE methods: (1) acoustic microscopy, (2) C-scan imaging, (3) axial backscattering, and (4) radial backscattering. The UE techniques exploited the variations in ultrasonic scattering produced by changes in the distribution of the SiC particles.
