Abstract
In this study, metal matrix composite materials containing melt-spun Al-20Si-5Fe alloys and boron carbide was produced by
high energy ball milling and then hot pressing at 200 MPa pressure and 450°C. Mechanical and microstructural characterizations
were performed by using an optical microscopy, X-Ray diffractometer, and dynamic microhardness tester. It was observed that
boron carbide particles were homogenously distributed in the microstructure and values of microhardness and elastic modules were
averagely 830 MPa and 42 GPa, respectively.
