摘要: SnO2 was successfully coated on the surface of alumina borate whiskers. The pure aluminum matrix composites reinforced with a SnO2-coated whisker were fabricated by squeeze casting. effects coating contents damping properties at various temperatures, frequencies, and strain amplitudes examined. microstructures also investigated through transmission electron microscopy observations. These results indicate that introduction Sn interface between in during casting process alters not only structures but dislocation status matrices vicinity interface. characterization capacities strongly depend amplitudes. A peak low temperatures appeared nonco...
