## Description

- description: Phase-field simulations are performed to investigate the martensitic
    transformation (MT) from body-centeredcubic-α to face-centered-cubic-γ′ when external
    compressive stress is applied along the [100]α direction, as well as the reverse
    MT from γ′ to α during the unloading of the external stress. The objective is
    to gain fundamental insights into the reversibility of the MT in Fe–Mn–Al–Ni alloy
    with a microstructure containing nanoscale β-NiAl precipitates in the α phase.
    The stress-induced MT from α to γ′ occurred under a compressive loading of approximately
    400 MPa, resulting in a martensite microstructure composed of two of the three
    crystallographic orientation variants. The elastic energy in the β phase increased
    owing to the MT, which slightly increased the structural density of martensite
    and consequently increased the chemical free energy of the β phase. Moreover,
    the structural density of martensite in the γ′ phase decreased near the β-phase
    boundary, where a compositional gradient was present, resulting in an increase
    in the chemical free energy of the γ′ phase. A complete reverse MT occurred when
    the total free-energy change, determined by the balance between the elastic-energy
    change and chemical free-energy change, temporarily became positive during the
    unloading of external stress.
