Abstract
This study has been performed to examine the deformation behavior and microstructure change in the spinning process of a magnesium alloy pipe. Spinning forming was conducted by an NC control machine at 300 ℃ with main shaft rotational frequency 300 rpm and feed per revolution 180 mm/min. Test specimen was a magnesium alloy pipe with outer diameter 100 mm and wall thickness 3 mm. Spinning forming was successful to form a dome part of pressure gas cylinder. Variation of wall thickness was examined in deformed part. Grain size refinement was confirmed by microstructure examination.
