Abstract

Since they are light in weight, have high corrosion resistance and can be alloyed to give strength values even higher than structural
steels, aluminum alloys are used in many sectors. With the developing technology, it is necessary to work in line with the
increasing quality expectations. In aluminum castings, modification studies are common practice such as grain refining with TiB among foundries to improve the final product quality. However, the reactivity to grain refinement and modification processes
in Aluminum alloys with different chemical components varies. In this study, the change in mechanical properties of the Al5Ti1B
sintered addition and Al10Sr modifying additive sand mold casting was investigated without the addition of the aluminum alloys
110, 140, 160, 177 of the Etial standard. In the study, chemical composition determination by spectrometer, microstructure
studies were examined. As a result of the experiments, it was determined that when grain refiner was added, the particle structure
was further thinner and the coarse dendritic structure disappeared. It is also clearly seen that the effect of the modifier varies
positively depending on the content of the eutectic Si in the structure.

Abstract

Alüminyum alaşımları
ağırlıkça hafif olması, yüksek korozyon dayanımı ve alaşımlandırılarak yapı
çeliklerinden bile daha fazla mukavemet değerleri kazandırılabilmesi gibi
özelliklerinden dolayı birçok sektörde kullanım alanı bulmaktadır. Gelişen
teknoloji ile birlikte artan ihtiyaç ve kalite beklentileri doğrultusunda
çalışmalar yapılması gerekmektedir. Alüminyum dökümlerinde nihai ürün
kalitesini artırmaya yönelik Ti-B ile tane inceltme, modifikasyon çalışmaları
dökümhaneler arasında oldukça yaygın uygulamalardır. Ancak farklı kimyasal
bileşimlere sahip Alüminyum alaşımlarının tane inceltme ve modifikasyon
işlemlerine tepkileri değişkenlik göstermektedir. Bu çalışmada Etial standardı
110, 140, 160, 177 alüminyum alaşımlarının ilavesiz olarak, Al5Ti1B tane
inceltici ilaveli ve Al10Sr modifiye edici ilaveli kum kalıba dökümünde
mikroyapı özellikler üzerindeki değişim incelenmiştir. Çalışmada spektrometro
ile kimyasal bileşim belirleme, mikro yapı incelemeleri gerçekleştirilmiştir.
Deneyler sonucunda tane inceltici ilavesi ile alaşımlarda tane yapısının daha
da inceldiği ve kaba dentirik yapısının bozunduğu tespit edilmiştir. Ayrıca
modifiye edicinin etkisinin yapı içerisindeki Ötektik Si içeriğine bağlı olarak
olumlu yönde değiştiği anlaşılmıştır.
