Nanotwinned titanium forges path to sustainable manufacturing

Posted On: 11/12/21

Titanium is strong and lightweight, boasting the highest strength to weight ratio of any structural metal. But processing it while maintaining a good balance of strength and ductility is challenging and expensive. Researchers at the Department of Energy's Lawrence Berkeley National Laboratory have discovered that they could use a technique called cryo-forging to manipulate pure titanium on the scale of a billionth of a meter (a nanometer) at ultra-low temperatures to produce extra-strong "nanotwinned" titanium without sacrificing any of its ductility.
