Yarı katı şekillendirilmiş AlSi12 alüminyum alaşımında Ag ilavesinin mikroyapıya etkisinin incelenmesi

Adnan Türker, Nurşen Saklakoğlu

Öz


Bu çalışmanın temel amacı yarı katı halde şekillendirilmiş AlSi12 alaşımına eser miktarda Ag elementi ilavesinin malzemenin mikroyapısına ve mekanik özelliklerine etkilerini ortaya koymaktır.  Yarı katı halde şekillendirmenin intermetalik morfolojisi, Si oluşumu ve küresel α-Al morfolojileri üzerinde önemli bir etkiye sahip olduğu sonucuna varılmıştır. İntermetalikler yarı katı halde şekillendirme esnasında kırılmaktadır. Ayrık Si partikülleri hem yarı katı hem de tikso şekillendirmede gözlenmiştir ve mekanik özelliklere önemli katkısı olmuştur.
