Thermal Deep Drawing of Magnesium Alloy Sheets

Thermal deep-drawing is a main processing technology which is used to plastic forming for magnesium alloy sheet. Combined with the research status, several deep drawing methods were introduced in detail in this paper, including indirect heating deep drawing, direct heating deep drawing, differential temperature deep drawing, warm hydraulic deep drawing, warm deep drawing with solid particles, warm deep drawing with segmental blank-holder, pre-forming warm deep drawing. Finally, the development trend and burning questions of magnesium alloy thermal forming technology were predicted.
