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.
