Magnesium powder of 5% by weight or less of the total weight of the mixed powder of these metal or nonmetal powders is added, and alloying is performed by a mechanical alloying method. As the magnesium powder, a commercially available powder having a reagent grade purity can be used. If more than 5% by weight of magnesium powder is added, the mechanical alloying powder becomes coarse and difficult to remove during sintering.

This compact can be subjected to a heat treatment at a temperature lower than the melting point of the alloy synthesized for the purpose of adjusting the structure or increasing the true density. Since the amount of magnesium remaining in the alloy is small, heat treatment can be performed without being limited by the heating rate or the heating temperature. The atmosphere during the heat treatment is preferably in a vacuum or an inert gas atmosphere in order to prevent oxidation or nitridation of the alloy.
