Heat-assisted Dieless Drawing for Light Metal Tubes

Abstract

The heat-assisted dieless drawing is utilized for light metal tubes such as aluminum, magnesium and titanium alloys. The geometrical similarity law in cross section of non-circular aluminum tube is satisfied in dieless drawing process. The large reduction in area of dieless drawing can be realized for magnesium alloy with hard deformable metal. Furthermore, titanium alloy tube with 180µm can be fabricated by dieless drawing process.
