摘 要：<正> Nanocrystalline alloy wlth graln size of about 10～20nm was prepared by mechanlcal alloying of elemen-tal powders in an imnliscible Ta-Cu system, The structure changes of Ta70Cu30 during mechanical alloyingwere monitored by X-ray diffraction. scanning electron microscopy and transmission electron microscopy.High-energy ball milling can efficiently reduce the grain size and considerably increase the Cu solubility in Ta.The significant enhancement of hardness of alloyed powders was also observed.
