Magnesium Scandium Alloy is an alloy composed of magnesium and scandium. It is strong, lightweight, and corrosion-resistant, making it ideal for a variety of applications. It has a high strength-to-weight ratio and is well-suited to applications such as vehicle structures, aerospace components, and sporting goods.
The main advantage of Magnesium Scandium Alloy is its strength-to-weight ratio. It is significantly lighter than other metals and alloys, yet has a comparable strength.
This makes it an ideal material for applications where weight reduction is critical, such as in aircraft and vehicle structures. In addition, it has excellent corrosion resistance, making it suitable for applications in harsh environments.
Another key benefit of Magnesium Scandium Alloy is its high ductility, which makes it suitable for a variety of fabrication processes, such as forging and casting. This allows the alloy to be formed into complex shapes and components.
It also has good machinability and weldability, making it suitable for joining components together. Magnesium Scandium Alloy is a relatively new alloy and is not widely used.
However, its unique properties make it suitable for a variety of applications, including those in the aerospace, automotive, and sporting goods industries. As more manufacturers become aware of its potential, its use is likely to increase.
The Global Magnesium Scandium Alloy Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A newly developed magnesium-scandium alloy with a bcc structure has been announced to display the superelastic effect at −150°C (−238°F) and a martensitic transition by Tohoku University in Japan.
It was verified that the Mg-20Sc alloy displays a superelastic strain exceeding 4% and 6% recoverable strain (comprising both superelastic and ordinary elastic strain). The stress-strain curve of the magnesium-sodium alloy sheet at −150°C (238°F) is depicted in the picture.
The sheet specimen was first loaded in tension to a 3% strain, and then it was released. The alloy sheet exhibits superelastic behaviour. A shape memory effect was also noted. The researchers discovered that manipulating the amount of scandium in a Mg-Sc shape-memory alloy can change its operating temperature.
They further verified that a Mg-Sc alloy with 18.3 at% scandium showed shape recovery upon heating from −30°C (−22°F) to room temperature.Compared to practical TiNi SMAs, the density of the Mg-Sc SMA is roughly 2 g/cm3, which is one-third less.
According to the analysts, this might have a big effect on the aircraft sector. Rockets and spacecraft use less fuel when their components are lighter. Thus, self-deployable space habitat frames and dampening components for spacecraft systems are just two aerospace applications for which this lightweight magnesium-based SMA has enormous potential.
Furthermore, SMAs based on magnesium can be used in the medical industry. Nowadays, self-expandable stents made of TiNi superelastic alloys are being employed with remarkable success.
But there’s the issue of restenosis within the stent.Biodegradable stents made of magnesium alloy have lately been presented as a way to overcome restenosis. This suggests the possibility of using the Mg-Sc superelastic alloy in biodegradable self-expanding stents. The biocompatibility and biodegradable qualities of the current alloy system will be assessed, and the alloy composition will be optimised to raise the working temperature.
