Spinodal decomposition, chemical and magnetic ordering in Cu–Al–Mn shape memory alloys
Single crystal alloys Cu-22.64 Al- 8.26 Mn and Cu-23.33 Al- 9.42 Mn (at. %) are studied by means of differential scanning calorimetry, electrical resistometry and thermomagnetic techniques. Order-disorder transitions were identified and the critical temperatures are compared with the values obtained...

| description | Single crystal alloys Cu-22.64 Al- 8.26 Mn and Cu-23.33 Al- 9.42 Mn (at. %) are studied by means of differential scanning calorimetry, electrical resistometry and thermomagnetic techniques. Order-disorder transitions were identified and the critical temperatures are compared with the values obtained by Monte Carlo simulations. Evidences of spinodal decomposition and magnetic transitions are discussed.
•Two Cu–Al–Mn alloys are characterized by DSC, ER and thermomagnetic techniques.•The temperatures of atomic ordering transitions are determined.•Atomic ordering temperatures are reproduced by means of Monte Carlo simulations.•Depending on the thermal treatment, one or two magnetic transitions are found.•An interpretation for the thermal hysteresis of the magnetic reaction is given. |
