Abstract
In order to uniformly distribute SiCp in the aluminium matrix and prepare SiCp/Al composites with high mechanical and damping properties, a preparation method of colloidal dispersion and suction filtration was developed. It was observed from the microstructure of the composites that the SiCp/Al composites prepared by colloidal dispersion and suction filtration method had good interfacial structures, and the interfacial reaction between SiCp and aluminium matrix was effectively inhibited. Tensile mechanical properties at room temperature and damping properties in the temperature range of 25 °C to 300 °C were tested for the SiCp/Al composites with volume fractions of 5% to 10%. The results showed that SiCp/Al composites have excellent mechanical and damping properties when the volume fraction of SiCp was 7%. This is because SiCp were uniformly distributed in the aluminium matrix, and formed a good interfacial bond with the aluminium matrix, which benefitted both the interfacial slip loss and the strengthening effect of SiCp.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
