Abstract The multimetallic cocktails provide vast compositional space with unlimited elemental combinations and structural possibilities for alloy design. The crystallographic metastability and thermodynamic instability offer opportunities for the activation of athermal transformations and intermetallic phase formation, particularly when exposed to mechanical perturbations and thermal input. Elemental interactions between the constituent and/or interstitial elements attribute to the remarkable interstitial strengthening effect. The associated strengthening mechanisms and strain-hardening mechanisms are also discussed. Here, we attribute the above-mentioned properties to cocktail effects, which is originated from the synergistic multicomponent alloying. These results provide the insights for the development of structural materials via cocktail effects.

了解面心立方高熵合金在环境温度和低温下的稳定性和性能的鸡尾酒效应

摘要 多金属混合物为合金设计提供了无限的元素组合和结构可能性的广阔组成空间。晶体亚稳定性和热力学不稳定性为激活无热转变和金属间相形成提供了机会，特别是在暴露于机械扰动和热输入时。成分和/或间隙元素之间的元素相互作用归因于显着的间隙强化效果。还讨论了相关的强化机制和应变硬化机制。在这里，我们将上述特性归因于鸡尾酒效应，它源于协同多组分合金化。
