%X 本文采用分子动力学方法对Al<sub>x</sub>CoCrFeNi高熵合金中不同Al含量(x = 0、5、10、15、20、25、30)的模型的凝固过程进行模拟实验。结果表明，Al含量的增加会使Al<sub>x</sub>CoCrFeNi高熵合金的结晶度和结晶度降低，并且当Al的含量在不同区间时，会使Al<sub>x</sub>CoCrFeNi高熵合金发生结晶时出现的晶粒结构不一样：在Al含量较低时形成FCC单相晶粒，在含量中等时形成FCC   BCC双相结构，在Al含量较高时会形成非晶结构。<br />
In this paper, the crystallization process of Al<sub>x</sub>CoCrFeNi high-entropy alloys modeled with different Al contents (x = 0, 5, 10, 15, 20, 25, and 30) is simulated using molecular dynamics method. The results show that the increase of Al content decreases the crystallinity and crystallinity of Al<sub>x</sub>CoCrFeNi high-entropy alloys, and when the content of Al is in different intervals, it will make the grain structure appearing in Al<sub>x</sub>CoCrFeNi high-entropy alloys when crystallization occurs is not the same: FCC single-phase grains are formed when the content of Al is low, the FCC   BCC dual-phase structure is formed when the content is medium, and in the case of Al at higher Al content, amorphous structure is formed.
