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.

Özet

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.
