Description

technical field [0001] The invention belongs to the technical field of light alloy melt processing, and particularly relates to a device and method for magnetically induced vibration solidification of light alloy melt. Background technique [0002] Vibration is a very effective way to change the solidification behavior of metals. For example, during solidification, the application of mechanical vibration, pneumatic vibration, electromagnetic vibration and ultrasonic vibration will affect the temperature field, flow field, concentration field, nucleation and growth of the alloy during the solidification process. Among them, mechanical vibration has a very significant effect on changing the solidification behavior of metals, and is one of the most commonly used methods in metal vibration solidification. Using a reasonable mechanical vibration mechanism to treat the alloy melt has a significant effect on refining grains, inhibiting dendrites and inhibiting the segregation of a...
