New Lightweight Metals

Science Daily: Exceptionally strong and lightweight new metal - Magnesium infused with dense silicon carbide nanoparticles could be used for airplanes, cars, mobile electronics and more

summary - A team led by researchers has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. To create the super-strong but lightweight metal, the team found a new way to disperse and stabilize nanoparticles in molten metals.
