ALLOY POWDER CONTAINING MOLYBDENUM AND TUNGSTEN AND USE THEREOF

摘要

The present invention relates to a process for the production of an alloy powder (Mo, W) for powder metallurgy, which comprises mixing molybdenum and tungsten in the form of compounds chemically or mechanically and reducing the mixed powder with hydrogen and a process for the production of a hard solid solution (Mo, W)C from the alloy powder (MO, W), which comprises carburizing further the alloy powder (Mo, W). The (Mo,W)C produced by the process of the present invention is a stable carbide and may favourably be used as a substituted for WC.
