Strong Super Metal Made of Magnesium
With Silicon Carbide Nanoparticles
So is the era of the new “Super Car”? The future transportation of superheros? UCLA Henry Samueli School of Engineering and Applied Science and a team of researchers have claimed that they have done it. With the help of this new super metal, airplanes, spacecraft, and cars will not only become lighter but stronger. For the more scientific readers, the UCLA super team found a new way to disperse and stabilize nanoparticles* in molten metals. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles*.

Next, Add Some Silicon Carbide
What is Silicon Carbide? Silicon Carbide is an extremely hard ceramic used in applications that require high endurance, such as bulletproof vests and car brakes. When the magnesium is infused with a large number of silicon carbide particles, the combination displayed record levels of specific strength, such as how much weight a material can withstand before breaking and durability under high temperatures.
Unfortunately, ceramic particles, although long considered to be a way to make metals stronger, under the infusion process results in plasticity loss. During the infusion process, the ceramic particles tend to clump together…hence, plasticity loss.
Kinetic Energy to the Rescue
To counteract the “clumping,” the UCLA researchers dispersed the ceramic particles into a molten magnesium zinc alloy relying on the kinetic energy to stabilize the particles dispersion. No more clumping. More plasticity.
What does this mean for the future of the automobile industry?
In short, this new super light and impressively strong game changing metal could turn the automotive industry on its head. Nanoparticle-enhanced metals could potentially cut fueling costs due to the lightweight composite, and only time will tell but – for Paintless Dent Repair companies – dents will become more manageable. Dent’s that couldn’t be removed with Paintless Dent Repair might now be put on the PDR menu!
