摘要: Isothermal treatments at 413 K were performed in Cu–Al–Mn shape memory alloy samples, to study their effects on the martensitic transformation. This procedure, within miscibility gap, produces spinodal decomposition. After each aging thermal treatment, transformation was monitored using Differential Scanning Calorimetry (DSC). Spinodal decomposition significantly changes characteristics of transition, reducing transformed volume and modifying critical temperatures. Furthermore, hysteresis loop narrows as fraction precipitates increases. Effects cycling through studied aged samples. It found that temperatures changes, an increase fraction, a wider loop. The observed results discussed considering interaction between plates.
