ARTICOLO A BASE DI UNA LEGA METALLICA DI NICHEL CROMO ED ELEMENTI META LLOIDI INCLUDENTE PRECIPITATI MICROCRISTALLINI LEGA METALLICA E METODO |
摘要 |
A description follows of an article based on a nickel-chromium-silicon metal alloy, including microcrystalline borides, obtained by the rapid solidification and subsequent thermal treatment at a temperature from 700 DEG C to 950 DEG C for 5 minutes to 100 hours of a nickel-chromium-boron-silicon metal alloy comprising from 39.0 to 69.4 atom % of nickel, from 11.8 to 33.9 atom % of chromium, from 7.6 to 27.4 atom % of boron and from 7.6 to 17.5 atom % of silicon. The above article is preferably a tape or a sheet or a fiber having high mechanical properties and is particularly resistant to oxidation to be used as substrate for the growth of superconductor oxides or as a reinforcing element in composite materials with an organic, metallic or pyroceram matrix. <IMAGE> |
