Spinodal decomposition, chemical and magnetic ordering in Cu–Al–Mn shape memory alloys

Publication date: 1 May 2020Source: Materials Chemistry and Physics, Volume 246Author(s): D. Velázquez, M.A.E. Chaparro, H.N. Böhnel, R. Romero, F. LanziniAbstractSingle 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.
