B4c Takvi̇yeli̇ Aa7075 Kompozi̇t Metal Köpük Üreti̇mi̇ Ve Karakteri̇zasyonu

Abstract

In this study, the production and characterization of open-cell composite metal foam using the replica method, also known as polymer impregnation, was investigated. Composite powders were prepared by alloying in a planetary ball mill for 1 hour using AA7075 aluminum powder and 10% by weight B4C powder. Characterization and morphology analysis of the composite metal foam produced using the prepared composite powders were performed using XRD and SEM/EDS analyses. As a result of the analyses, it was observed that α-Al, B4C, C phase as a result of the polyurethane sponge not being completely removed from the structure, and secondary and tertiary phases such as Al3BC, AlB2, AlB12C2 and Al3B48C2 resulting from the sintering process were observed in the composite foam metal structure.
