Abstract

There have been reports on sheet forming of Mg alloy in industry via the punch and die method. This paper is probably the first formal one for studying the AZ31 sheet formability of employing pressurized gas to press the sheet into a female die cavity at various elevated temperatures. The results indicate that it is feasible to form a rectangular box via pressurized gas from extruded sheets with the thickness of 0.5 or 1.7 mm. The formed box has the depth to width ratio of 1:2, which should be large enough when dealing with realistic industrial sheet forming parts. Presently, forming a sheet of 0.5 mm thick is considered a technical challenge by industry, and it has been conquered as demonstrated in this paper. The application of the gas forming technique to Mg alloy is unprecedented and it has a great potential for the industrial utilization.
