Az31b Magnesium Alloy Sheet

The formability of the magnesium alloy sheets is poor at room temperature even though the magnesium alloy sheets are attractive because of their excellent characteristics. Hydro-forming technology, especially the pulsating hydro-forming, may be a way to improve the formability. Finite element simulations have been conducted to investigate the formability of AZ31B magnesium alloy sheet in hydro-bugling by pulsating hydraulic pressure. The influence of linear pressure, pulsating pressure and pulsating frequency on the maximum bulging height and minimum wall thickness of the formed parts have been analyzed. The research results show that the formability of AZ31B magnesium alloy sheet can be improved dramatically by pulsating hydro-forming. And enough bugling height can be obtained by lesser forming hydraulic pressure. The AZ31B sheet has an excellent performance in formability when the pulsating frequency is properly selected.

Welded Seam

Magnesium alloy tailor-welded blanks(MTWBs) of AZ31 and AZ80 sheet had been manufactured by gas tungsten arc welded(GTAW), which the thickness were 0.8mm. The welding properties of Magnesium alloy sheet had been analyzed, and the technology parameters of GTAW were determined by experiment study, which was that welding thread being Φ2.0mm, welding electricity 50A, welding voltage 9V, welding rate 12—13cm/min. The research results presented that the grain in welded seam was isometric crystal, and the grains were branching crystal in heat-affected zone (HAZ). For MTWBs of AZ31and AZ80 sheet which the thickness was 0.8mm, the forming parameters were that the forming temperature of AZ31 being 190-220°C, and forming temperature of AZ80 being 310°C-350°C, and the temperature of tools is 180°C~200°C.
