Structure and thermal stability of rapidly solidified alloys with elements from deep-sea nodules

Novák Pavel - University of Chemical Technology in Prague (Czech Republic)

Deep-sea nodules are composed predominantly of oxides and hydroxides of manganese and other elements, such as iron, nickel or copper. All of these elements have a significant influence on aluminium alloys, while manganese forms quasicrystalline phases with aluminium during rapid solidification. In this work, the product of aluminothermic reduction of deep-sea nodules was added to aluminium in various amounts and the alloys were processed by rapid solidification by the means of melt spinning method. The structure, phase composition and thermal stability during long-term annealing were described.
