Powder Metallurgy Processing of Magnesium and Its Alloys

Abstract

In this study, the usability of powder metal magnesium alloys in industrial applications was investigated. It is well known that there are difficulties in the plastic deformation of magnesium, due to its hexagonal closed package crystal structure. So it is thought that powder metallurgy can be used to overcome these aforementioned problems. Hence, the studies on the powder metallurgy processing of magnesium alloys were compiled. The findings of the studies on eliminating the surface oxide layer formed during the production of magnesium particles are summarized. As a result, when more sophisticated methods or secondary processes are used rather than press-sinter methods, it is possible to produce Mg alloys with higher strength than that of casted counterparts. Also, it is expected that in the near future along with the development of new kind of particulate material processing methods  (such as selective laser sintering, direct energy deposition) Mg alloys will be used in much greater amounts.

Magnezyum ve Alaşımlarının Toz Metalurjisi İşlemleri

Abstract

Bu çalışmada, günden güne daha geniş alanlarda kullanılan magnezyum tozmetal alaşımların endüstriyel uygulamalarda kullanılabilirliği incelenmiştir. Bu malzemenin hegzagonal sıkı paket kafes yapısından dolayı plastik deformasyonunda yaşanan zorlukları aşmak için geleneksel plastik deformasyon yöntemleri yerine toz metalurjisi yöntemi ile şekillendirilebilirliği hakkında literatürde bulunan çalışmalar derlenmiştir. Özellikle magnezyum partiküllerinin üretimi sürecinde oluşan yüzey oksidi tabakasının elimine edilmesi için kullanılabilecek yöntemlerle ilgili çalışmaların bulguları özetlenmiştir. Sonuç olarak press-sinter yöntemine göre daha sofistike yöntemler veya ikincil işlemler kullanılması durumunda döküm alaşımlarına göre daha yüksek dayanım gösteren Mg alaşımlarının üretiminin mümkün olduğu ve gelişen partikül malzeme üretim yöntemleri (Seçici lazer sinterleme, direkt enerji biriktirme gibi) ile birlikte yakın gelecekte tozmetal magnezyum alaşımlarının daha geniş alanlarda kullanılacağı öngörülmektedir.
