An article of the Economist about new IRON-ALU alloys made with nanotechnologies, will this be a revolution in weapons making?
A LOT of tosh is talked about “nanotechnology”, much of it designed to separate unwary investors from their hard-earned cash. This does not mean, though, that controlling the structure of things at the level of nanometres (billionths of a metre) is unimportant. In materials science it is vital, as a paper just published in Nature, by Hansoo Kim and his colleagues at the Pohang University of Science and Technology, in South Korea, demonstrates. 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. . . . .
