SiC fiber reinforced superplastic Zn-Al alloy (SiC/SPZ) composites were fabricated by a metallurgical technique in which ultrasonic vibration was applied. Fiber breaking in the composites during tensile testing were detected by an acoustic emission technique in order to analyze the mechanism of strengthening induced by modification of microstructures. The fracture resistance of composites to failure is enhanced by homogeneous arrangement of fibers. Homogeneous arrangement of fibers and preferable penetration of matrix metals to the interstices among fibers which are induced by superplasticity and ultrasonic vibration result in strengthening of SiC/SPZ composites, even if the volume fraction of fibers remains unchanged.
