<p>TITLE OF THE INVENTION A process for the production of a hard solid solution containing molybdenum The present invention relates to a process for the production of a solid solution constructed of at least one hard phase having a crystal structure of simple hexagonal type and selected from mixed carbides or carbonitrides of molybdenum and tungsten, which process comprises preparing an alloy powder consisting of a solid solution of molybdenum and tungsten, adding to the alloy powder carbon in an amount necessary for forming (Mo, W)2C and/or (Mo, W)2(CN), heating the mixture at a temperature at which (Mo, W)2C and/or (Mo, W)2(CN) is stable, adding to the (Mo, W)2C and/or (Mo, W)2(CN) carbon in an amount necessary for forming (Mo, W)C and/or (Mo, W)(CN) optionally with an iron group metal and then heating the mixture at a temperature at which (Mo, W)C and/or (Mo, W)(CN) is stable.</p> |
