Manufacturing Technology of Magnesium Alloy Bicycle Parts

摘要

One kind of deformed magnesium alloy with high strength and high plasticity was made to be bicycle parts. Meantime, the microstructure and mechanical properties of the magnesium alloy were analyzed. In addition, the deformation and welding technology of taper pipe and shaped tube of bicycle were studied. The results showed that the bicycle parts manufactured through extruding and welding of the new type magnesium alloy have high strength, good plasticity. The tensile strength can reach 321.3 MPa and the elongation is more than 20%. By adopting the new welding process of internal mending and cuttage grafting, the after-welding-strength is 90.2%. of the base metal Meanwhile, the industrialization level can meet the requirements of European Union (EU) vehicle standards.
