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.

评估 Al-16Si-4Cu-10SiC 复合材料/Al-4Cu-Mg 合金接头中的工具转速效应

本研究探讨了带有圆柱螺纹销的工具转速对 Al-16Si-4Cu-10SiC 复合材料/Al-4Cu-Mg 合金接头的微观结构、机械性能和耐腐蚀性能的影响。结果表明，在热输入小于 121 J/mm 和大于 342 J/mm 的情况下，隧道缺陷在前进侧形成。随着转速从 800 转/分增加到 1000 转/分，硅颗粒尺寸和长宽比分别从 5.6 ± 1.2 微米和 0.6 增加到 3.5 ± 1.4 微米和 0.8。将转速从 1000 转/分降低到 800 转/分后，硬度（152.3 ± 0.6 HV0.1）、屈服强度（383 ± 6 兆帕）、极限抗拉强度（469 ± 9 兆帕）和腐蚀率（1.03 毫米/年）均达到最大值。
