主 题：Medium-entropy alloy undercooling microstructure mechanical properties
摘 要：Undercooling of ternary CoCrNimediumentropy alloy(MEA)was achieved by molten glass fluxing *** influence of undercooling on microstructure and mechanical properties of was *** microstructure changes during the undercooling process identified by transmission electron microscope and scanning electron microscope shows that the grain size and intergranular phase all change after the undercooling *** yield strength of the ternary MEAincreased significantly after undercooling treatment,which attribute to the refined grain size and the formation of the new *** method can be used as a potential method to modify the microstructure and improve the mechanical properties of MEAs.
