抄録

In order to fabricate Mg-based composite powders with high hardness and hard magnetic properties, pure magnesium and barium ferrite powders were mechanically alloyed (MAed) using a vibrational ball mill.<BR>Change in Vickers micro-hardness of the pure magnesium powders as a function of the mechanical milling (MM) times obeyed the crystallite size. Change in Vickers micro-hardness of the composite powders as a function of the amount of barium ferrite obeyed the rule of mixture when the MA time was 120 and 240 min.. On the other hands, change in Vickers micro-hardness of the composite powders as a function of the amount of barium ferrite wasn't obeyed the rule of mixture when the MA time was 20 and 60 min.. Magnetization of the composite powders obeyed the amount of the barium ferrite powder, whereas coercive force of the MAed powders decreased due to the refinement of the barium ferrite powder.<BR>Mg-based composite powders with high hardness and hard magnetic properties were successfully produced by mechanical alloying.
