New Materials in Aerospace Engineering: Metallic Glass

Aerospace Engineering Metallic Glass

Material specification in aerospace engineering is critical. Beyond design and operational issues using applicable material during production is important. In this manner research and development studies about are still going on. In aerospace engineering next generation of production and new borders of production is strongly related with material limits.

Price, mechanical specifications and physical details are important for a material that used in aerospace engineering production. Alloys and composites are common materials for aircraft application. However new material types are under development. Metallic glass is one of the next generation materials in aerospace engineering which has top engineering capabilities.

Lighter Material for Aerospace Engineering

In aerospace engineering production light and strong materials are need to be used during production. Metallic glass can be next generation of light and strong material. It is stronger than titanium and lighter than zirconium. By using metallic glass it is available to have 20% lighter composites. It has less density than common aerospace engineering materials.

Metallic glass has amorphous structure. Atoms metallic glass structure is packed randomly in metallic glass. And it is made by combination of metals and ceramics like zirconium, copper, nickel and others. Amorphous structure of metallic glass led to have elasticity. By using proper production methods having non-deformable pieces is possible. Strength to weight ratio of metallic glass doubles alloys of magnesium, titanium and aluminum.

Another benefit of metallic glass is ease of production. Because of amorphous structure having near net shape product is easier. Manufacturing methods that used in plastics can be used for metallic glass. Military applications can be first production of metallic glass.

Using metallic glass as raw material is not only solution for aircraft production. It can be new horizon of composite materials. There is alternative ways and criteria for tweaking components and pushing performance borders.

Aerospace Engineering and Limitations of Metallic Glass

However metallic glass that can be used in aerospace engineering has fatal limitation. Pushing borders of mechanical performance fails in a short time. Metallic glass has aging problem. Incredible properties of metallic glass lost because of aging. Research and development projects about long life metallic glass are still under development. Using different elements in bath and changing composition of alloy are common methods to have longer life.

Metallic glass is a product of metal and glass optimization. It has novel processing region: Taking durability of metal and lightness of ceramic. Try and fail period of metallic glass is still going on. Metallurgy and refractory studies need to collaborate for material of future. Beyond research and development studies there are different commercial applications for consumer goods. Shielding and gear mechanics can be application fields of metallic glass in aerospace engineering.
