# Ohio State engineers crystal defects to strengthen cobalt alloys

> Ohio State researchers reported that organizing crystal defects into dense networks strengthened two metal alloys without changing their chemical composition. The study, published in Science on October 15, examined a cobalt-nickel superalloy and a cobalt-chromium-tungsten alloy.

The team deformed the crystals and then thermally aged them, examining atomic structures with electron microscopy and computer simulations. Results showed improved resistance to stress and gradual deformation at high temperatures. Turbine and power-plant components are potential applications; the source reports neither commercial deployment nor a quantified lifetime gain.
