Abstract采用传统座滴法研究了低熔点合金(Bi-Sn)和高熵合金(AlCoFeNiCr和CuCoFeNiCr)之间的润湿行为及界面特征。借助扫描电子显微镜(SEM)和能谱分析(EDS)分析了Bi-Sn/AlCoFeNiCr和Bi-Sn/CuCoFeNiCr界面微观结构。结果表明:AlCoFeNiCr和CuCoFeNiCr高熵合金都是结构单一的固溶体,但Bi-Sn熔体在CuCoFeNiCr高熵合金基体上的润湿性明显地优于Bi-Sn熔体在AlCoFeNiCr高熵合金基体上的润湿性;Bi-Sn/CuCoFeNiCr界面发生剧烈的化学反应,有大量的界面反应物生成,Bi-Sn熔体中的原子Sn主要是沿着CuCoFeNiCr高熵合金中的富铜相扩散,而Bi-Sn/AlCoFeNiCr界面平直,且随着润湿温度的升高,Bi-Sn熔体中的原子向AlCoFeNiCr高熵合金基体的扩散程度加强并伴随化学反应,出现类似"皮下潜流"现象;由于CuCoFeNiCr高熵合金中富铜相的存在,为Bi-Sn在CuCoFeNiCr高熵合金基体上的铺展提供了"润湿通道"。
Other AbstractThe wetting behavior and the interracial characteristics of the molten Bi-Sn on the A1CoFeNiCr HEA (high entropy alloy) and the CuCoFeNiCr HEA substrate were investigated by a sessile drop method. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS) were used to analyze the microstructure of the Bi-Sn/AICoFeNiCr HEA and Bi-Sn/CuCoFeNiCr HEA interface. The results show that the A1CoFeNiCr HEA and the CuCoFeNiCr HEA form with a single solid solution structure. However, Bi-Sn molten alloy on CuCoFeNiCr HEA substrate has better wetting characteristics than Bi-Sn molten alloy on A1CoFeNiCr HEA substrate. With increasing wetting temperature, a number of intermetallic compounds are generated at the interface between the molten Bi-Sn and the CuCoFeNiCr HEA substrate, and the diffusion of Sn atom along the Cu-rich solid-solution phase in CuCoFeNiCr HEA is much more intense. On the contrary, the interface of the Bi-Sn/AICoFeNiCr HEA system is still the straight interface, and there are new intermetallic compounds on the Bi-Sn/A1CoFeNiCr HEA interface with increasing wetting temperature. It is found that the Cu-rieh phase in CuCoFeNiCr HEA provides a "wetting channel" for the wetting process between the molten Bi-Sn and CuCoFeNiCr HEA substrate, which result in the two wetting systems with different wetting mechanisms.
