论文摘要
高熵合金增加了一个新的维度，原子尺度的随机性和相关的比例依赖性组合物波动，以传统的冶金轴轴测 - 体温 - 复合 - 微生物结构。合金性能由缺陷的能量和运动控制（位错，晶界，空缺，裂纹等）。原子量表的随机性可以引入可以控制缺陷行为的新长度和能量尺度，从而控制合金特性。因此，原子尺度随机性的轴结合了多组分合金中巨大的组成空间，因此可以与仍然存在的传统原理同时进行，这是一种新的更广泛的合金设计策略，可以帮助实现许多工程应用的多表现要求。
High entropy alloys add a new dimension, atomic-scale randomness and the associated scale-dependent composition fluctuations, to the traditional metallurgical axes of time-temperature-composition-microstructure. Alloy performance is controlled by the energies and motion of defects (dislocations, grain boundaries, vacancies, cracks, ...). Randomness at the atomic scale can introduce new length and energy scales that can control defect behavior, and hence control alloy properties. The axis of atomic-scale randomness combined with the huge compositional space in multicomponent alloys thus enables, in tandem with still-valid traditional principles, a new broader alloy design strategy that may help achieve the multi-performance requirements of many engineering applications.
