| titleOfInvention |
Dispersions of nitrides in a metal or alloy and their method of preparation |
| abstract |
THE DISPERSIONS ARE CHARACTERISED BY THE FACT THAT THE PARTICLES OF SINGLE OR MIXED NITRIDES ARE DISTRIBUTED UNIFORMLY IN THE MIDST OF THE SELECTED BASE METAL OR ALLOY. TO MANUFACTURE THESE DISPERSIONS A MXED OXIDE, A COPRECIPITATE OF HYDROXIDES OR A MIXED COMPLEX OF A FIRST METAL PROVIDING THE NITRIDE AND OF A SECON METAL PROVIDING THE BASE METAL ARE SUBJECTED TO A HEAT TREATMENT IN AN ENCLOSURE IN AN ATMOSPHERE SIMULTANEOUSLY REDUCING AND NITRIDING OF HYDROGEN AND AMMONIA OR NITROGEN. THE HEAT TREATMENT IS CARRIED OUT AT LESS THEN 1100*C. TO WHICH THE STARTING MATERIALS ARE BROUGHT AT A SPEED OF 100 TO 400*C./HOUR. THESE DISPERSIONS ARE USED IN CONVENTIONAL TECHNIQUES OF POWDER METALLURGY. |
