Abstract

Bu çalışmada, Al7050 serisi talaşlardan sıcak
ekstrüzyon yöntemi ile %5 B4C takviyeli kompozit malzeme üretimi
gerçekleştirilmiştir. Deneysel çalışmalar başlangıç olarak Al7050 serisi bulk
malzemelerden freze tezgâhında talaş üretimi ile başlamıştır. Üretilen talaşlar
aseton ve alkol banyosundan geçirildikten sonra kurutma işlemleri ile
temizlenmiştir. Daha sonra Al7050 serisi talaşlara ağırlıkça %5 oranında B4C
parçacıkları ilave edilerek bilyeli öğütücüde 5 saat boyunca homojen bir
karışım sağlanmıştır. Elde edilen karışım 600 MPa basınç altında 550oC
sıcaklıkta tek yönlü olarak sıkıştırılarak biyet hale getirilmiştir. Çalışmada
sıcak presleme yöntemi ile üretilen biyetler 550oC sıcaklıkta
ısıtıldıktan sonra ekstrüzyon işlemine tabii tutulmuştur. Ekstrüzyon sonrası
üretilen kompozit çubuk numunelerin mikro-mekanik özellikleri derinlik duyarlı
sertlik ölçme testleri ile analiz edilmiştir. Numuneler üzerinde farklı pik
yükleri (2.94, 1.96 ve 0.98 N) altında derinlik duyarlı Vickers indentasyon
testleri uygulanmıştır. Numunelerin mikro-mekanik özelliklerini değerlendirmek
için yük (P)-penetrasyon derinliği (h) eğrileri analiz edilmiştir.
