摘要：

In this study, the foaming behavior of metal matrix composites (MMCs) containing micron-and nano-sized TiB2 particles was compared. Foaming was achieved by adding blowing agent into the MMC melt at 670 degrees C. Macrostructural and microstructural characterization of the foams were performed by using X-ray tomography and scanning electron microscopy. Quasi-static compression tests were conducted to analyze the mechanical behavior of the foams. Foams stabilized by nanoparticles showed higher expansion than those stabilized by micron -sized particles indicating a better stabilization by nanoparticles. The foams containing nanoparticles also exhibited better mechanical properties. This is mainly due to the presence of nanoparticles in the microstructure.
