Abstract:

In this study, the production of AA 2014 aluminum alloy and B4C-SiC ceramic particle supplementary hybrid metal matrix composite materials, microbuilding and mechanical characteristics were studied. For this purpose, SiC (%5-10-15), B4C (%5-10-15) and B4C-SiC (%10-10) in different volumes are made in the aluminum matrix structure of compound and hybrid compound materials supplemented with ceramic particles. Matrix and supplemented powder mixtures are one-way pressed in the form of bloc samples below 700MPa, and synthesized at a temperature of 600oC in the Argon atmosphere for 1 hour. The experimental samples performed in production are characterized by the measurements of SEM (Intermediate Electron Microscope), Optical Microscope and Micro Hardness (HV 0.1). Depending on the volume increase of the B4C and SiC ceramic particles, it is detected by micro-structure images in which a homogeneous distribution in the aluminum matrix structure is shown.  According to AA 2014 aluminum alloy, it has been found that hardness values have increased due to the increased SiC and B4C ceramic particle additive rate. In B4C-SiC particle supplemented hybrid composite materials, the microhardness value has been relatively reduced compared to the single ceramic phase supplement containing 15% B4C and 15% SiC.
