AbstractThis article discusses the possibility to produce hybrid workpieces from aluminum alloys AMg2, AMg5, and AMg6 using combined upsetting deformation with a surface shear (torsional upsetting). The finite element simulation of shape formation using the QForm 10.1.5 software has been applied. The obtained rheological models of deformed materials and the specially developed friction.sliding_velocity subroutine have allowed us to obtain simulation results agreeing well with the experimental data. Metallographic studies have confirmed the high joining quality of workpieces in the contact area.
