doi:10.3901/JME.2023.22.254

Abstract

Abstract: The high-rate impact welding process of Al3003 aluminum and HC180 steel dissimilar metals is taken as the research object, and a coupling model of two-dimensional finite element(FEM) algorithm and smooth particle dynamics(SPH) algorithm is established to investigate the interface waveform formation. The results show that, the waveform amplitude of Al-steel impact joint interface increases with the increase of impact velocity. With the enlargement of impact angle, the amplitude of interface waveform increases first and then stabilizes or even decreases. The simulation results are verified by foil vaporization impact welding experiments, and the influence of discharge energy on the morphology of the Al-steel joint interface is analyzed. The interface waveform amplitude increases with the enhances of welding discharge energy. When the energy reaches 8.4 kJ, vortex structure and embedded particles appears at the interface. Obvious grain refinement will occur near the interface, and with the increase of impact angle, the area of fine grain region near the interface will gradually increase. The simulation analysis of the interface temperature field showed that, temperature rise in the vortex structure, and electron probe analysis(EPMA) results show that, the Al-steel intermetallic compounds generated in these zones. Intermetallic are mainly embedded in the base metal matrix in the form of particles or distributed in the interface vortex structure. With the increase of the initial impact angle, the element diffusion intensifies, and the embedded particle size and embedded depth increase.
