Abstract

Bu çalışmada, magnezyum oksit (MgO)ilave edilmiş alüminyum (Al) - MgO kompozitler toz metalurjisi yöntemiyle üretilmiştir. Kompozitlerde MgO güçlendirici olarak ağırlıkça %10 oranında ilave edilmiş olup güçlendiricinin ortalama çapı <40 nm boyutundadır. Kompozitler, karıştırma, sıkıştırma ve 5 saat sinterleme süresi ile farklı sinterleme sıcaklıklarına (500 oC – 550 oC – 600 oC) tabi tutulmuşlardır. Kompozitlerin mikroyapıları optik mikroskop ve taramalı elektron mikroskobu (SEM) aracılığıyla incelenmiştir. Kompozitlerin teorik yoğunlukları karışım kanununa göre ve ölçülen yoğunlukları Arşimed prensibine göre araştırılmıştır. Teorik yoğunluk değerleri ve ölçülen yoğunluk değerleri kullanılarak ürünlerin porozite içeriği belirlenmiştir. Ayrıca kompozitlere sertlik testi uygulanarak mekanik özellikleri araştırılmıştır. MgO nano partikül alüminyum matrsinin sertliğini önemli derecede arttırmıştır. Maksimum sertlik değeri Al-10 MgO kompozitte 104 HB olarak elde edilmiştir. Tane büyümesi sertlikte liner büyümeyi engellediği görülmüştür. Artan sıcaklıkla kompozitlerde tane büyümesi meydana gelmekte, porozite içeriği azalmakta ve sertlikte farklı değerler elde edilmektedir. Maksimum relatif yoğunluk 600 oC sintermele sıcaklığı ile elde edilmiştir.
