Effect of fullerene (C60) nanoparticle on mechanical properties of hot-extruded aluminum matrix composite

Abstract

Aluminum matrix composites have attractive attention for scientists and manufacturers. In this study, fullerene (C60) nanoparticle reinforced aluminum matrix composite was fabricated via semi powder metallurgy method. Development of mechanical performance of pure aluminum was aimed using C60 nanoparticle. Microstructure analyzes were completed by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM). Hardness, compression and tensile properties of unreinforced aluminum and C60 reinforced composite were evaluated. Results show that nanoparticle was homogenously distributed in matrix and there were no cracks or macro defects. Hardness was significantly improved with the addition of fullerene and extrusion process. Al-C60 composite exhibited better compression and tensile performance than pure aluminum.

FULLERENİN SICAK EKSTRÜZYONLU ALUMİNYUM MATRİSLİ KOMPOZİTİN MEKANİK ÖZELLİKLERİNE ETKİSİ

Öz

    Alüminyum matrisli kompozitler sanayiciler ve bilim insanları için dikkat çekici bir öneme sahiptir. Bu çalışmada fulleren (C60) takviyeli alüminyum matrisli kompozit malzeme, yarı toz metalürjisi yöntemiyle üretilmiştir. X Işını Kırınımı (XRD) ve Taramalı Elektron Mikroskopuyla (SEM) numunelerin mikro yapı analizleri gerçekleştirilmiştir. Saf alüminyum ve Al-C60 kompozitinin sertlik, basma ve çekme mukavemetleri hakkında değerlendirmeler yapılmıştır. Sonuçlardan yola çıkarak, fullerenin alüminyum matrisi içerisinde homojen dağıldığı gözlemlenmiştir ve herhangi bir çatlağa ya da makro hatalara rastlanmamıştır. Fullerenin ilavesiyle ve ekstrüzyon prosesiyle alüminyumun sertliğinde önemli bir artış görülmüştür. Al-C60 kompoziti saf alüminyuma kıyasla daha iyi basma ve çekme mukavemeti performansları sergilemiştir.
