A team of researchers from the Henry Samueli School of Engineering at the University of Applied Sciences in Los Angeles in the US, has created an innovative metal of high strength and low density made by 86% magnesium and 14% of silicon carbide particles according to the study published in the journal ‘ Nature ‘.
Strong and light, Researchers create a revolutionary new Metal
To create the so-called ‘Nanoparticles Metal’, the team developed a new method to disperse and stabilize nano-particles in molten metals. Equally possible to develop a method that could lead to the manufacture of lightweight materials and similar high performance. The low density and high strength magnesium showed, record levels of specific resistance (amount of weight that resists material before breaking) and specific module (ratio between rigidity and weight) both low and high temperatures.
It’s been proposed that nanoparticles could really enhance the strength of metals without damaging their plasticity, especially light metals like magnesium, but no groups have been able to disperse ceramic nanoparticles in molten metals until now,” Xiaochun Li, the principal investigator on the research said in a press release.
This new procedure opens the door for improving existing materials used in the aviation, space and automotive industries, among others, by including nano-particles that improve their performance in extreme conditions to meet energy and sustainability challenges in today’s society if one takes into account that magnesium is an abundant resource, and therefore its use does not cause environmental damage.
