Abstract:SiC-fiber-reinforced Al-Mg matrix composites with different mass fractions of Mg were fabricated by combining colloidal dispersion with a squeeze melt infiltration process. The microstructure, mechanical and damping properties, and the corresponding mechanisms were investigated. Microstructure analyses found that SiCf/Al-Mg composites presented a homogeneous distribution of SiC fibers, and the relative density was higher than 97% when the mass fraction of Mg was less than 20%; the fiber–matrix interface bonded… Show more
“…Insufficient damping capacity has notably restricted their applications in vibration-sensitive environments. Lin et al [ 14 ] investigated the mechanical and damping properties of SiC f /Al-Mg composites with varying Mg contents. These composites were fabricated using colloidal dispersion combined with a squeeze-melt infiltration process.…”
