NON-NEWTONIAN MAGNETOHYDRODYNAMC MULTIPHASE FLOWS IN SOLIDIFYING ALUMINIUM MATRIX COMPOSITES
摘要
The working principle of a new electromagnetic rheocaster, which is based on the use of rotating permanent magnets and which allows the production of intense three-dimensional multiphase flows in solidifying semi-solid alloy slurries and metal matrix composites, is described. Local measurement techniques are applied to the study of the evolution of non-newtonian magnetohydrodynamic multiphase flow phenomena with the rotational speed of the inductor, the solid fraction of the aluminum alloy matrix and the size and volume percent of SiC particles. A discussion is presented relating the metallurgical findings to the heat and three-phase flow measurements.
