- Abstract
- This paper proposes the net-shape forging process for the magnesium (Mg) scroll which is a device for compressing air or a refrigerant in air-conditioning equipment or an automobile supercharger Mg scrolls make it possible to reduce the total weight of the scroll compressor noticeably by replacing the aluminum scroll in the compressor fields. In order to manufacture the sound scroll with uniform wrap height the optimum back-pressure is applied to the Mg scroll forging, which is calibrated from the finite element analysis using DEFORM-3D. It is concluded that dimensional accuracy of the final product of the Mg scroll is comparably good since the all wraps are extruded more than the minimum machining line. It is also noted that the experimental and simulation results are able to be the best agreement with consideration of the texture evolution and DRX of the Mg alloy during the warm forging process.
