Preparation of semisolid AlSi7Mg alloy slurry through weak traveling-wave electromagnetic stirringZhen-duo Zhao,Wei-min Mao,Sha Li,and Rong-mao Zhong School of Materials Science and Engineering,University of Science and Technology Beijing,Beijing 100083,China摘 要:The semisolid AlSi7Mg alloy slurry with large capacity was prepared by low superheat pouring......
uniformly and become into globularity or strip. Because the inner gate limits the flowing of semi-solid slurry, and the pressure acted on the semi-solid slurry decreases gradually along the filling direction of semi-solid slurry in cavity, microstructural segregation of unmelted α-Mg grains appears along this direction. Shrinkage holes in casting are caused by two different reasons. For biscuit......
