Abstract A perturbation model is used to evaluate the phase stabilities of high entropy alloys. The calculation results can successfully predict the phase stabilities of many high entropy alloys and shows that stable single phase high entropy alloys are rare. The effect of increased entropy cannot balance the fast-increased driving force for the formation of intermetallics. As the temperature increases, the stabilities of solid solutions will increase and the portion of single-phase alloys will expand. The model we propose provides a new paradigm to understand the phase stabilities of high entropy alloys.

高熵合金的相稳定性

摘要 微扰模型用于评价高熵合金的相稳定性。计算结果可以成功预测许多高熵合金的相稳定性，表明稳定的单相高熵合金很少见。熵增加的影响不能平衡金属间化合物形成的快速增加的驱动力。随着温度的升高，固溶体的稳定性会增加，单相合金的比例会扩大。我们提出的模型为理解高熵合金的相稳定性提供了新的范式。
