A new manufacturing technique ensures microcrystalline structures inside high-performance materials remain intact when processed.rnResearchers at the Fraunhofer Institute for Manufacturing Engineering and Applied Materials Research in Dresden developed the technique for aluminium alloys but it could also be used for other materials.rnAluminium alloys built with microcrystalline structures are stronger and firmer than regular aluminium. The alloy's properties, which are mainly a result of the tiny size of its crystals, are ideal for parts such as automobile screws and pistons that undergo high stress and temperatures.
