Notes:
Thixo-forming is in the forefront of metal processing technology in the 21st century. Theresearch on thixo-co-extrusion of multi-layer tube as extension and development of the semi-solidforming technology is a completely new processing method for the composite material forming andis of great significance, in which different semi-solid billets (slurries) are extruded at the same timeto form multi-layer tubes. In this study, different sizes of column-shaped and ring-shaped billets ofAl/Mg alloys were firstly prepared by using specially designed molds. Then they were reheated byelectric-resistance furnace,microstructures from different heating laws were investigated. Lastly,FEM simulation on thixo-co-extrusion of double-layer tube with A356/AZ91 was conducted
