To date, most identifications of the as-quenched microstructure of the Cu[sub 2]MnAl alloy were performed by using the x-ray diffraction method, magnetometry, scanning electron microscopy and resistometry. No transmission electron microscopy (TEM) was used. Therefore, the purpose of this work is to study the as-quenched microstructure of the Cu[sub 2]MnAl alloy by TEM. Based on the present study, they found that a high density of extremely fine 2H-type precipitates could be detected within the L2[sub 1] matrix in the as-quenched alloy. The 2H phase has not previously been observed by other workers in the Cu-Mn-Al ternary alloy system.
