PROBLEM TO BE SOLVED: To provide a method for manufacturing alloy powders overcoming disadvantage of well-known technical level.SOLUTION: The method for manufacturing alloy powders based on titanium, zirconium and hafnium alloyed with elements Ni, Cu, Ta, W, Re, Os and Ir is provided in which an oxide of Ti and/or Zr and/or Hf is mixed with a metal powder of the above elements and with a reducing agent, and this mixture is heated in a furnace under argonate atmosphere or, optionally under hydrogen atmosphere (forming metal hydrides in the process), until the reducing reaction begins. In the method, the oxide used has an average particle size (FSSS) of 0.5 to 20 μm, a specific surface area by BET of 0.5 to 20 m/g and a minimum content of 94 mass%. |
