Abstract

Secondary aluminum become prominent due to production costs and environmental issues of primary aluminum. However, inclusions and impurities included in secondary aluminum causes avoiding excess amount of secondary aluminum in fabricating critical parts. In this work, while vibrating the mould whether these inclusions were floated or not and whether solid part under these porosities and inclusions were produced or not were preliminarily explored. Concurrently, effect of vibrating on solidification was investigated. Variations of dendrite morphologies during solidification were examined using optical microscope. DAS and SDAS were measured.

Özet

Birincil alüminyumun üretim maliyetleri ve çevresel etkileri göz önünde bulundurulduğunda ikincil alüminyum öne çıkmaktadır. Ancak içerdiği katışkılar (inklüzyonlar) veya kirlilikler neticesinde ikincil alüminyumun da kritik parçaların üretiminde kullanılmaktan kaçınılmaktadır. Bu çalışmada titreşim altında katılaşma yapılarak bu kirliliklerin titreşimin etkisi ile yüzeye doğru yükseltilmesi ve altta kalan nihai döküm parçasının sağlam şekilde imal edilip edilemeyeceğinin bir ön araştırması yapılmıştır. Aynı zamanda titreşimin katılaşma karakteristiğine de etkisi incelenmiştir. Işık mikroskobu kullanılarak katılaşma esnasında dendritlerin morfolojisi değişimi incelenmiştir. Dendrit kolları arası mesafe ve ikincil dendrit kolları arası mesafeler ölçülmüştür.
