A cobalt aluminum nanolaminate has shattered the usual tradeoff between strength and flexibility, emerging up to 10 times stronger than structural steel without becoming dangerously brittle. Jet engines demand materials that can survive tremendous heat and force without bending, cracking, or slowly losing their shape. The strongest candidates, however, often come with a major weakness: [...]from SciTechDaily https://ift.tt/LWlyIZE
