摘要：

The phase decomposition microstructure during continuous cooling of Mn-30at.%Cu alloy was studied using X-ray diffraction analysis and transmission electron microscopy (TEM). The composition of the Cu-rich fraction was stabilized by the 10h cooling. A longer cooling time may increase the volume fraction of the Cu-rich phase and trigger the precipitation of the αMn phase on the grain boundaries. The spinodal nature of the phase decomposition in the primary stages was confirmed by TEM observations.
