The materials key to many important applications in aerospace and energy generation must be able to withstand extreme conditions such as high temperatures and tensile stresses without failing. Now a team of MIT-led engineers reports a simple, inexpensive way to strengthen one of the key materials used today in such applications. Further, the team believes that their general approach, which involves the 3D printing of a metallic powder strengthened with ceramic nanowires, could be used to improve many other materials. “There is always a significant need for the development of…
