摘要
研究了中熵合金 Co17.5Cr12.5Fe55Ni10Mo5(at%)在低温范围(包括低至 0.5 K 的创纪录低温区域)内的力学性能和微观结构演变。研究证实,低温塑性变形引发了该合金的马氏体相变,而动态弹性模量值与相变程度相关。
Low-Temperature Elastic Properties of Molybdenum Doped Non-Equiatomic High Entropy Alloys of the Fe-Co-Ni-Cr System
The mechanical properties and microstructural evolution of a medium-entropy alloy Co17.5Cr12.5Fe55Ni10Mo5 (at%) in a low temperature range (including the record low temperatures region down to 0.5 K) were investigated. It has been established that low-temperature plastic deformation initiates martensitic phase transformations in this alloy, and the values of the dynamic modulus of elasticity correlate with the degree of phase transformations.
