Study on Preparation and Refining Efficiency of Al-5Ti-1C Master Alloy Refiner

Article Preview

Abstract:

Al-5Ti-1C master alloy refiner was prepared by melt reaction method, and its refining efficiency was examined by purity aluminum in the paper. The microstructures under different process conditions were studied by OM, SEM and XRD. The results shown that the grains were finer, TiAl3 and TiC phases were uniformly distributed at 900¡æ, held time for 15min. The refining efficiency was best at addition of 0.4% (wt.%) refiner and held time for 10min.
