Abstract
The effect of isothermal ageing at 300 °C on the characteristic transformation temperatures and structure changes in Cu-Al-Mn alloys containing 1.5-9 wt% Mn have been studied by differential scanning calorimetry and transmission electron microscopy. Alloys containing 5-6 wt% Mn were least affected by ageing treatment, since changes of Ms were observed only after several hours of ageing. Changes in Ms are attributable to ordering in all the alloys and to matrix composition changes subsequent to formation of γ in low Mn alloys or bainite in high Mn alloys.
