“…The microstructures were refined by the alloy melt rheological solidification under high pressure. Studies have shown that the rheological solidification structures are closely related to the fluctuation intensity of alloy melt [30][31] . With the increase of rheological distance, the rheological rate of alloy melt is reduced because of the energy consumption caused by rheological resistance.…”

S queeze casting can be supposed as a combination of casting and forging [1, 2]. In this process, high pressure is applied to the melt during solidification to obtain fine grains. The essence of mold-filling and feeding is rheological solidification of the alloy melt under pressure. Microstructure evolution is inevitable in this process, which affects the mold-filling and feeding in turn. Therefore, research on microstructure evolution during the rheological process under applied pressure is extremely meaningful. A great deal of scientific research has been done on the mechanism of microstructure evolution [3-10]. The basic methods of refining microstructure are: controlling nucleation, inhibiting dendrites growth, and prompting the initial solidification nucleation [3]. Based on these ideas, various techniques, such as mechanical stirring [4] , electromagnetic stirring [5] , strain induced melt activation [6] , casting using a cooling slope [7-9]
