Abstract
This study investigated the influence of the rotational speed of the tool with a cylindrical threaded pin on the microstructure, mechanical properties and corrosion resistance of the Al-16Si-4Cu-10SiC composite/Al-4Cu-Mg alloy joint. The results show tunnel defects are formed on the advancing side in the heat input less than 121 J/mm and more than 342 J/mm. With the increase of rotational speed from 800 to 1000 rpm, the silicon particle size and the aspect ratio have decreased and increased from 5.6 ± 1.2 to 3.5 ± 1.4 µm and 0.6 to 0.8, respectively. By decreasing rotational speed from 1000 to 800 rpm, the maximum hardness (152.3 ± 0.6 HV0.1), yield strength (383 ± 6 MPa), ultimate tensile strength (469 ± 9 MPa) and corrosion rate (1.03 mm/year) were achieved.
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.
