摘要:
中熵合金材料由于多组元结构表现出高强度、高塑性和低温下良好的断裂韧性，但其力学性能在高温下仍然较差，限制了在工程中的应用。以CoCrNi中熵合金为例，综述了其力学性能的特点，并简述了CoCrNi中熵合金相应的变形机制。同时，讨论了添加合金元素、预塑性变形与优化制造工艺这3方面因素对中熵合金力学性能的影响。最后，提出了中熵合金在实际生产应用过程中可能面临的问题。
Abstract:
The medium entropy alloy exhibit high strength, high plasticity and good fracture toughness at low temperatures due to their multi-component structure, however, its mechanical properties do not perform well at high temperature, which limits its application in engineering area. Taking CoCrNi medium entropy alloy as an example, the characteristics of mechanical properties and the deformation mechanism of CoCrNi medium entropy alloy are summarized. The effects of the addition of alloying elements, pre-plastic deformation and optimization of manufacturing process on the mechanical properties of the medium entropy alloy are discussed. Finally, the possible problems in the actual production and application of the medium entropy alloy are presented.
