Development of Microstructure of Semi-Solid 6061 Alloy with Method of Alternating Electromagnetic Stirring
The semi-solid 6061 alloy was obtained with method of alternating electromagnetic stirring. The results show that compared with horizontal, vertical and spiral magnetic stirring method, alternating magnetic stirring could make eligible slurry with finer, more equiaxed and more homogeneous primary α particles in much shorter time. The microstructure evolution during isothermal treatment is studied and it is shown that the average particle diameter increases with the increase of isothermal holding time and the shape coefficient decreases somewhat at first, and then decreases sharply in the end.
