TOZ METALURJİSİ YÖNTEMİYLE ÜRETİLEN AL2024 ve AL6061 MATRİSLİ, GRAFEN – KARBON NANOTÜP ve TİTANYUM DİOKSİK TAKVİYELİ KOMPOZİT MALZEMELERİN MİKROYAPI ve MEKANİK ÖZELLİKLERİNİN İNCELENMESİ
INVESTIGATION OF MICROSTRUCTURE AND MECHANICAL PROPERTIES OF AL2024 AND AL6061 MATRIX, GRAPHENE - CARBON NANOTUBE AND TITANIUM DIOXIDE REINFORCED COMPOSITE MATERIALS PRODUCED BY POWDER METALLURGY METHOD

Summary/Abstract: In this study, the microstructure and mechanical properties of composite materials produced by powder metallurgy method by reinforcing Graphene, Carbon Nanotube (CNT) and Titanium dioxide (TiO2) particles into aluminum powders with Al2024 and Al6061 matrices were investigated. The reinforcement and matrix powders calculated by weight are mixed in a three-dimensional mixer and transferred to a mold of 3.170 x 1.270 x 0.625 mm. Pressing is applied to the mold with a force of 540 MPa. In order for the product to gain the desired strength, sintering is performed in the range of 600 - 610 oC. Microstructure analysis was examined using Scanning Electron Microscope (SEM), a generally homogeneous distribution was observed within the structure. When the samples were examined in terms of mechanical properties, it was observed that the hardness and tensile strength increased with the increase of reinforcement materials. When compared in terms of mechanical properties and matrix elements, it was concluded that the resulting materials also showed better mechanical properties than Al6061 composites, Al2024 composites.
