摘要：
The milling behavior of nickel aluminide, NiAl, powder in the presence of a fine Al2O3powder was investigated in the present study. The milling was carried out in an attrition mill. The size and shape of NiAl particles were not changed after milling while only NiAl powder was milled. When fine Al2O3powder was added to the NiAl powder, the Al2O3particles attached to the surface of NiAl particles during milling. As a consequence, the size of NiAl particles was reduced after milling. The shape of NiAl particles also changed. The presence of fine Al2O2particles enhanced the milling efficiency. The Al2O3particles on the surface of NiAl powder can be removed by washing repeatedly in an ultrasonic bath.
