## Description

- description: "The exceptional mechanical properties of Ni-based high entropy alloys
    are due to the presence of ordered L12 (\U0001D6FEʹ) precipitates embedded within
    a disordered matrix phase. While the strengthening contribution of the \U0001D6FEʹ
    phase is generally accepted, there is no consensus on the precise contribu-tion
    of the individual strengthening mechanisms to the overall strength. In addition,
    changes in alloy composition influence several different mechanisms, making the
    assessment of alloying conditions complex. Multicomponent L12-ordered single phase
    alloys were systematically de-veloped with the aid of CALPHAD thermodynamic calculations.
    Alloying elements, Co, Cr, Ti, and Nb were chosen to complexify the Ni3Al structure.
    The existence of the \U0001D6FEʹ single phase was validated by microstructure
    characterization and phase identification. High temperature com-pression test
    from 500 °C to 1000 °C revealed a positive temperature dependence of strength
    before reaching the peak strength in the studied alloys: NiCoCrAl, NiCoCrAlTi,
    and NiCoCrAlNb. Ti and Nb alloying addition significantly enhanced the high temperature
    yield strengths before the peak temperature. The yield strength was modeled by
    summing the individual effects of solid solution strengthening, grain boundary
    strengthening, order strengthening, and cross-slip-induced strengthening. Cross-slip-induced
    strengthening was shown to be the key contributor to the high temperature strength
    enhancement."
