基于位错动力学的高熵合金辐射诱导脆化研究

Research on irradiation embrittlement effect of high entropy alloy based on dislocation dynamics

 

实习内容:

高熵合金因其良好的力学性能,耐腐蚀性能和抗辐照性能,被认为是未来有前景的核结构材料。在辐照条件下,高熵合金会产生硬化和脆化,基于位错动力学阐明高熵合金辐照诱导脆化机制,对于未来评估高熵合金服役行为,预测期寿命和制备抗辐照性能的高熵合金具有重要意义。因此,本实习主要通过位错动力学计算阐明各种类型辐照损伤缺陷的尺寸、密度与位错的相互作用,及其对脆化行为的影响。

High-entropy alloys (HEAs) are considered as promising nuclear structural materials in the future because of its good mechanical properties, corrosion resistance and radiation resistance. The mechanism of irradiation-induced embrittlement based on dislocation dynamics is of great significance for evaluating the service behavior of HEAs, predicting their lifetime and preparing high-entropy alloys with anti-radiation properties. Therefore, the interaction between radiation damaged defects and the dislocation and their effects on the embrittlement behavior will be elucidated through the calculation of dislocation dynamics in this practice.
