Introduction

The ternary system is the basis for many engineering alloys, such as grain refined cast Al-alloys, aluminization of steels, soft magnetic alloys for transformers etc. In addition, iron and silicon originating from bauxite ore and anode materials are present in nearly all industrial Al-alloys, and the metallurgical grade silicon contains, among others, aluminum and iron as impurities.
