Abstract

Bu çalışmada, saf alüminyum ve ağırlıkça %0.1, %0.3 ve %0.5 oranında grafen nanotabaka (GNT) katkılı alüminyum (Al) matrisli kompozitler farklı sinterleme sıcaklıklarında (TS=550, 600, 630 °C) toz metalurjisi metoduyla üretilmiştir. Üretilen kompozitlerin deneysel yoğunluğu ve gözenekliliği Arşiment yoğunluk ölçüm kitiyle, Vickers sertliği mikro Vickers sertlik ölçme cihazıyla ve mikroyapısı taramalı elektron mikroskobuyla analiz edilmiştir. Test sonuçlarına göre; en iyi deneysel yoğunluk (2.52 g/cm3), gözeneklilik oranı (%6.7), Vickers sertliği (57±2 HV) TS=630 °C sinterleme sıcaklığında ve Al-%0.1GNT kompozit yapıda elde edilmiştir.

Investigation of the Effect of Sintering Temperature on the Density, Porosity, Hardness, and Microstructure of Graphene-Reinforced Aluminum Matrix Composites

In this study, pure aluminum and graphene nanoplatelets (GNPs) reinforced aluminum (Al) matrix composites with various graphene ratio (0.1, 0.3 and 0.5wt.% ) and different sintering temperatures (TS=550, 600, 630 °C) were fabricated by powder metallurgy method. Experimental density and porosity of the composites were performed by Archimedes’ density meter kit. Also, Vickers hardness and microstructure of the composites were determined by micro Vickers hardness tester and scanning electron microscope, respectively. Test results showed that the best experimental density (2.52 g/cm3 ) and porosity (%6.7), and Vickers hardness (57±2 HV) were obtained at the sintering temperature (TS=630 °C) and Al-0.1%GNPs composite.
