Abstract

In this study, the microstructural properties and hardness of five different commercial aluminum alloys containing various amount of Zn and Mg have been investigated. After production, the alloys were solutionized at 500°C for 1 hour and subsequently aged at 200°C for 1, 4 and 16 hours.
Microstructural properties such as size, amount, distribution and morphology of constituent phases were not much changed with respect to aging condition or Zn and Mg content. However, certain amount of coarsening was observed in the microstructures of 16 h aged all specimens due to overaging. After aging treatment, the hardness values of all investigated compositions increased significantly. For all compositions, the peak hardness was observed for 4 h aged specimens.

FARKLI Zn ve Mg İÇERİĞİNE SAHİP YAŞLANDIRILABİLİR TİCARİ ALÜMİNYUM ALAŞIMLARININ YAPISAL ÖZELLİKLERİNİN İNCELENMESİ

Abstract

Bu çalışma kapsamında, farklı oranlarda Zn ve Mg içeren 5 adet ticari Al döküm alaşımının mikroyapısal özellikleri ve sertlik değerleri incelenmiştir. Alaşımlara üretildikten sonra 500°C sıcaklıkta 1 saat süre ile çözeltiye alma işlemi uygulanmış sonrasında 200°C sıcaklıkta 1, 4 ve 16 saat boyunca yaşlandırma ısıl işlemine maruz bırakılmıştır. Mevcut fazların miktarı, dağılımı, büyüklüğü ve morfolojisi gibi mikroyapısal özellikler alaşımların bileşimine ve yaşlandırma işlemi süresine göre pek fazla değişmemiştir. Sadece 16 saat yaşlandırma sonucu mikroyapıda aşırı yaşlandırmaya bağlı irileşme gözlemlenmiştir. İncelenen tüm alaşımların sertlik değerleri yaşlandırma sonucu önemli ölçüde artmış olup tüm alaşımlar pik (en yüksek) sertlik değerlerine 4 saat yaşlandırma süresinde ulaşmışlardır.
