Abstract

Abstract: Conventional arc-melting and casting is the most widely used synthesis method of high-entropy alloys (HEAs). However, the extremely high melting temperature and repetitious melting processes cause the evaporation of some constituent elements with a low melting temperature, resulting in inaccurateness of composition. In this work, in-situ high throughput synthesis of FeCoNiCrCuAl x was carried out in the transmission electron microscope. The dynamic melting process of FeCoNiCrCu with Al was recorded, and the composition of FeCoNiCrCuAl x was examined by an energy dispersive spectrometer. The in-situ high throughput method provides a novel way to prepare HEA samples efficiently. Graphical abstract:
