A New Probe to Study the Mechanical Alloying Process of Cu-Zn Powder Mixtures

<正> Mechanical alloying (MA) as a novel powder processing technique has at-tracted increasing interest in basic research and in many applications.High energy ball-milling converts an initial powder blend into a composite powder with controlled microstructure. The introduction of iron impurities from the steel balls and/or the vial during the hall-milling processing is undesirable and unavoidable. However, the
