Abstract
Bu çalışmada Mg metaline Al ve Si elementlerinin ilavesi ile bir döküm yapılmıştır. Döküm sırasında atmosfer kontrollü bir döküm fırını kullanılmıştır. Alaşımda saf Mg metaline ilave olarak ağırlıkça %15 Al12Si ingot alaşımı kullanılmıştır. Elde edilen alaşım homojenleştirme sonrası numune haline getirilmiştir. Mg-Al-Si üçlü alaşımı şeklinde hazırlanan alaşım döküm sonrası klasik metalografik yöntemlerle hazırlanmış ve SEM ile mikroyapı incelemesi yapılmıştır. Ek olarak alaşıma elementel analiz uygulanmıştır. Temel mekanik değerler için alaşım Vickers tipinde sertlik testi ölçümüne alınmıştır. Alaşım mikro yapısında oluşan intermetalik fazların dağılımı ve yapıları incelenmiştir. Sonuç olarak standart (AS serisi) bir Mg alaşımı elde edilmiş ve temel özellikleri rapor edilmiştir.
