摘要: The as-quenched microstructure of the Cu-25at.%Al-7.5at.%Mn alloy was D0(3) phase containing extremely fine L-J precipitates (the L-J phase is a new type of precipitate, which was firstly observed and identified by Liu and Jena (designated L-J phase) in a Cu-2.2-Mn0.8Al alloy.). When the as-quenched alloy was aged at temperatures ranging from 500 degrees C to 700 degrees C, the phase transition sequence was found to be (gamma-brass + L-J + D0(3)) (gamma-brass + L-J + B2) -> beta This result is different from that reported by previous workers in Cu-25at.%Al-(0-8)at.%Mn alloys.
