摘要

作为一种平面缺陷，堆积断层很少被研究。定量评估堆叠断层（SFs）与强度之间的相关性仍不明确。在本研究中，我们对堆积断层能量（SFE）极低的非硅原子 CoCrNi 合金进行了特定真实应变下的拉伸试验，并对变形微观结构进行了表征。研究了堆积断层间距、堆积断层密度和堆积断层强化量化的特征。这项工作为堆叠断层强化的定量计算提供了合理的参考。

Quantifying the strengthening effect of stacking faults in a nonequiatomic CoCrNi alloy

As a kind of planar defect, stacking faults are seldom explored. Quantitatively evaluating the correlation between stacking faults (SFs) and strength remains unclear. In the present work, we conducted tensile tests at specified true strains and characterized deformation microstructures for a nonequiatomic CoCrNi alloy with very low stacking fault energy (SFE). Characteristics of stacking fault spacing, stacking fault density, and stacking fault strengthening quantification were investigated. This work provides a reasonable reference for the quantitative calculation of stacking fault strengthening.
