AbstractAluminium alloys have wide spread application areas from foil to wheel and also aluminium alloys have been the primary material of choice for structural components of aircraft since about 1930’s [1]. AlSi8Cu3Fe is the most popular and common choice for die casting. AlSi8Cu3Fe is known for offering an ideal combination efficient material properties and production workability. In addition, this material is commonly used by industrial applications throughout the World. It is suitable for large, intricate and thin walled castings in all types of moulds, also used where corrosion resistance or ductility is required. AlSi8Cu3Fe, being a hypoeutectic alloy close to Al– Si eutectic composition [2]. The microstructure of this cast alloy is composed of primary - aluminium dendrites and eutectic islands (acicular Si crystals in aluminium) [2].
