erice 732 Posted February 5, 2015 Share Posted February 5, 2015 By manipulating the structure of steel on a nanometre scale, Dr Kim has produced a material which has the strength and the lightness of titanium alloys but will, when produced at scale, cost a tenth as much. An alloy of iron, aluminium and carbon (steel’s other essential ingredient) is too brittle to be useful. Adding manganese helps a bit, but not enough for aluminium-steel to be used in vehicles. Dr Kim and his colleagues have, however, found that a fifth ingredient, nickel, overcomes this problem http://www.economist.com/news/science-and-technology/21642107-alloy-iron-and-aluminium-good-titanium-tenth Link to post Share on other sites
Guest Ketchup Posted February 6, 2015 Share Posted February 6, 2015 With nickle I would presume it woulb be less prone to rust. Sounds good though. Especially for hull construction? Link to post Share on other sites
