   Bu çalışmada, Al-Cu ötektik alaşımına %2 (ağ.)
 oranında Ag, Sn ve Zn metalleri katkılanarak
elde edilen Al-%33Cu-%2x [x=Ag, x=Sn, x=Zn] (ağ.)  alaşım sistemlerinin mikroyapı, mekanik ve
elektriksel özellikleri araştırılmıştır. Bu amaçla üçlü alaşımlar, belirlenen
oranlardaki metallerin vakum ortamında eritilmesinden sonra, eriyik haldeki
sıvı alaşımların döküm fırınındaki grafit potalara doldurularak
hazırlanmıştır.  Döküm halindeki
alaşımların, mikroyapı fotoğrafları taramalı elektron mikroskobu (SEM) yardımıyla
çekilmiştir. Çekilen bu fotoğraflardan, katkı elementlerinin mikroyapılara olan
etkileri araştırılmıştır. Al-%33Cu-%2x alaşımlarının kimyasal bileşim analizi
EDX ile yapılmıştır. Döküm halindeki Al-%33Cu-%2x [x=Ag, x=Sn, x=Zn] (ağ.)
alaşımları için mikrosertlik (HV) değerleri sırasıyla 184,6 kg/mm²,
144,2 kg/mm² ve 136 kg/mm²,  çekme dayanımı (s) değerleri 92
MPa, 72,7 MPa ve 53,7 MPa, elektriksel özdirenç (r)
değerleri ise 2,13x10^-8 mΩ, 3,47x10^-8 mΩ ve
3,07x10^-8
mΩ
olarak ölçülmüştür. Katkılama elementlerinin Al-Cu ötektiğinin mekanik ve
elektriksel özelliklerini etkilediği görülmüştür. Bu çalışmada bulunan deneysel
sonuçlar, literatürdeki benzer çalışmaların sonuçları ile karşılaştırılmıştır.
