Abstract

Magnesium alloys have received increasing attention due to their low density and high specific strength. Magnesium has hexagonal closed packet crystal structure at all temperatures and therefore it is very difficult to give shape to the magnesium by using conventional plastic deformation methods. One of the methods that can be used to overcome this poor deformability problem is using powder metallurgy. In this study, a non-commercial powder metal magnesium alloy was developed and the properties of the alloy were investigated. It has been observed that the addition of Sn to magnesium decreased the grain size and hence increased the hardness values. Also formation of the Mg2Sn phase contributed to the achievement of the higher hardness values. It was determined that the addition of tin makes it possible to reach the higher density values even by sintering conducted at the lower temperatures

Özet

Magnezyum alaşımları özellikle düşük yoğunlukları ve yüksek spesifik dayanımları nedeniyle günden güne daha geniş alanlarda kullanım imkanı bulmaktadır. Bu alaşımların endüstriyel uygulamalarda daha yüksek oranda kullanımının önündeki en büyük engel hegzagonal sıkı paket olan kristal kafes yapısından dolayı geleneksel yöntemlerle plastik deformasyon işlemlerinin zor olmasıdır. Bu zorlukların üstesinden gelmek için kullanılabilecek yöntemlerden biri toz metalurjisi (TM) ile üretimdir. Bu çalışmada ticari olmayan bir tozmetal magnezyum alaşımı toz metalurjisi yöntemiyle geliştirilmiş ve geliştirilen alaşımın mikroyapısal özellikleri incelenmiştir. Çalışma sonucunda magnezyuma yapılan Sn ilavesi ile tane boyutunda ve dolayısıyla sertlik değerlerinde yükselme tespit edilmiştir. Ayrıca magnezyuma yapılan Sn ilavesi ile Mg2Sn fazının oluştuğu görülmüştür. Kalay ilavesi ile daha düşük sıcaklıklarda yapılan sinterleme işlemlerinde yüksek yoğunluk değerlerine ulaşılabildiği tespit edilmiştir.
