Abstract Scope |
BCC refractory high-entropy alloys (RHEAs) made of group 4-6 refractory transition elements have superior high-temperature strength and structural stability. However, a systematic alloy design method has not been established. Meanwhile recently, a Unique alloy design method has been reported for extracting RHEA from solidified microstructure obtained from a multi-component alloy. In order to expand this design, it is essential to check the solidification behavior depending on the multi-component alloy composition. but solidification sequence analysis has not been clearly identified yet.
In our study, we investigated the solidification sequence of 9 and 8-component alloys and tried to understand the relationship between solidification behavior differences depending on the composition of the multi-component alloy and the resulting RHEAs composition. Through this study, we can find a total of 20 RHEAs alloys. Our research has presented a new paradigm in the design of alloys for RHEAs by extending the method of designing alloys selected by nature. |
