Effect of Magnetic Suspension Force in Electromagnetic Stirring on Microstructure of Al-Si Alloy () 摘要:Based on Maxwell equations, the Lorentz force in Al-Si alloy melt was calculated during the process of electromagnetic stirring using analytic approximation method. The effects of magnetic suspension force on the microstructure of Al-Si alloy were given under different electromagnetic......
