| Abstract: | To improve the welding performance of SiCp/6061Al,arc-ultrasonic technology was applied in welding process,and the filling material was Al-15Ti-3Si.The mechanism of arc-ultrasonic on microstructures of joint of SiCp/6061Al MMCs in plasma arc "In-situ" welding with different arc-ultrasonic frequency was investigated.The result shows that the Al3Ti phase is obviously refined by ultrasound.With the frequency 30,50 and 60 kHz,the Al3Ti is crushed to granular or block,and uniformly distributed in the weld.With the frequency 20,40,70 kHz,the Al3Ti is partially crushed,and distributed at the original location along the vertical in the weld.Analysis shows that the arc-ultrasonic impacts the morphology and distribution of Al3Ti mainly by cavitation and acoustic streaming. |
