Abstract：

In order to investigate the influence of upper plate thickness on the mechanical properties of self-piercing riveting （SPR）between HC340/590DP high-strength steel and AlSi10MnMg die-cast aluminum alloy, the elongation of AlSi10MnMg die-cast aluminum alloy was improved by heat treatment, and then riveted with HC340/590DP high-strength steel of different thicknesses,and the mechanical properties of joints were tested. The experimental results show that when using the T7 heat treatment process, AlSi10MnMg die-cast aluminum alloy has optimal riveting formability, with an elongation of 19%, which is 72% higher than the as cast elongation (11%). During the riveting process, the pressure of the rivet piercing the upper plate increases with the increasing of upper plate thickness. When the thickness of upper plate is 0.8-2.0 mm, the failure load of SPR joint first increases and then decreases with the increasing of upper plate thickness, and has the functional relationship: y=e-1.02x2+ 3.41x-0.57. When the thickness of upper plate is 1.6 mm, the SPR joint has the maximum failure load (9.8 kN) and the maximum energy absorption value (31.7 kJ).
