Özet
The hypereutectic Al-Si-Fe alloys are a kind of the structural materials used for high temperature applications [1, 2]. They are used in different kinds of industries such as automotive, military and aerospace because of some properties good castability, low density, good thermal conductivity, high strength etc.[3]. Fe-containing intermetallic compounds dispersed in the microstructure make Al-Si-Fe alloys durable at elevated temperatures. However, there are generally large brittle Fecontaining intermetallic compounds and coarse Si phases in the microstructure of conventional cast-Al-Si-Fe alloys. The phases such as Fe-bearing intermetallics and Si which display coarse and needle-like morphologies are harmful in terms of mechanical properties because of the stress concentration produced at the end of the acicular phase during the deformation process. Therefore, modification of Si phases and neutralization of detrimental effects of Fe-containing phases in hypereutectic Al-Si-Fe alloys have been investigated considerably to obtain optimum mechanical properties. In the literature, different kinds of production techniques are used to modify primary and eutectic Si and Fe-bearing intermetallics such as gas atomization and spray deposition [5, 6]. It is also reported that methods of melt spinning (MS) and high energy ball milling (HEBM) can be used a refined and modified microstructure in Al-Si alloys. On the other hand, method of HEBM can also be used to prepare metal matrix composites reinforced with ceramics because it is an effective way to improve reinforcement distribution in matrix. Boron Carbide (B4C) is commonly used as reinforcement …
