The precipitation of γ1 phase modifies the characteristics of the martensitic transformation in Cu-based shape memory alloys. In the early stage of decomposition, the knowledge of elastic constants of γ1 phase is of special interest due to the elastic interaction between martensite interfaces and precipitates. In this letter, neutron powder diffraction, differential scanning calorimetry, and accurate resonant ultrasound spectroscopy allow us to determine two different stages at the beginning of the γ1 phase precipitation process in a texture-free Cu–Al–Ni shape memory alloy. The elastic constants and Debye temperature of the γ1 phase in Cu–Al–Ni have been determined. [ABSTRACT FROM AUTHOR] |
