Magnesium is the least dense engineering metal, with an excellent stiffness-to-weight ratio. Magnesium recycling is important for both economic and environmental reasons. This project demonstrates feasibility of a new environmentally friendly process for recycling partially oxidized magnesium scrap to produce very pure magnesium at low cost.
Magnesium silicide is used to create aluminium alloys of the 6000 series, containing up to approximately 1.5% Mg 2 Si. An alloy of this group can be age-hardened to form Guinier-Preston zones and a very fine precipitate, both resulting in increased strength of .
Magnalium powder also burns with a crackling sound if burnt by itself, and provides a good compromise between the reactivity of magnesium, and the stability of aluminium. Another benefit for pyrotechnics is the brittleness of the alloy, as mentioned before. It is

Magnesium alloy strips are widely used in aerospace, automotive industry, etc., which are difficult to produce through cold forming process due to their poor deformation ability. In this article, we studied whether the rolling process with heated roll could be used to roll cold magnesium alloy strips.
Development of technological production process of biocompatible magnesium tubes for medical appliions is the subject of the present paper. The technology consists of two stages—extrusion and dieless drawing process, respectively. Mg alloys for medical appliions such as MgCa0.8 are characterized by low technological plasticity during deformation that is why optimization of production

In this study, the formability of AZ31B magnesium alloy sheets was investigated through experimental and numerical approaches. Tensile tests and limit dome height tests were carried out at several temperatures between 25 °C and 300 °C to obtain the mechanical properties and forming limit diagram (FLD). The interfacial heat transfer coefficient between two adjacent tools, and the convection

The Pidgeon process is one of the methods of magnesium metal production, via a silicothermic reduction. Practical production requires roughly 35–40 MWh/ton of metal produced, which is on par with the molten salt electrolytic methods of production, though above the 7 MWh/ton theoretical minimum.
Step 1： Dolomite ore is crushed and heated in a kiln to produce a mixture of magnesium and calcium oxides, a process known as calcining: Step 2： The next step is reduction of the magnesium oxide. The reducing agent is ferrosilicon (an alloy of iron and silicon) which is made by heating sand with coke and scraps iron, and typically contains about 80% silicon.
