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......
AN IN SITU SURFACE COMPOSITE AND GRADIENT MATERIALOF Al-Si ALLOY PRODUCED BY ELECTROMAGNETIC FORCE T.X.Li1,Z.L.Zhu1,Y.H.Zhou1,Z.M.Xu1 (1.School of Materials Science and Engineering, Shanghai Jiao Tong University, Shanghai 200030, China) Abstract:Because of the different conductivities between the primary phase (law electric conductivity) and the metal melt, electromagnetic force scarcely acts......
