Abstract

Powder metallurgy (PM) is a production method that offers manufacturers great advantages over
other manufacturing processes. Little changes in the production steps of powder metallurgy method
such as powder manufacture, powder processing, pressing, sintering affect the properties of the final
product significantly. Aluminum alloys are second most used alloy in the engineering applications.
Nowadays some parts in the automotive sector are produced with aluminum PM alloys. In the future,
it is expected that more Al-PM parts will be produced with the development of new high strength
Al based PM alloys. In this study, information about the production of the Al-PM parts is given and
some examples about the sintering of Al-Cu, Al-Si and Al-Mg PM alloys from the relevant literature
are presented. Properties of the various sintered PM Aluminum alloys are highlighted.

Alüminyum ve Alaşımlarının Toz Metalurjisi İşlemleri

Abstract

Toz metalurjisi (TM), üreticilere diğer imal usullerine göre büyük avantajlar sunan bir üretim yöntemidir. Bu yöntemin aşamaları olan toz üretimi, toz işleme, presleme, sinterleme ve sinterleme sonrası işlemlerdeki küçük farklılıklar nihai ürün özelliklerini büyük oranda etkilemektedir. Alüminyum
alaşımları günümüzde en çok kullanılan ikinci mühendislik alaşımıdır. Günümüzde otomotiv sektöründe bazı alüminyum parçalar TM uygulamaları ile üretilmektedir. Yüksek dayanımlı alüminyum
TM alaşımlarının geliştirilmesi ile ileride daha fazla sayıda parçanın bu yöntemle üretilmesi beklenmektedir. Bu çalışmada, alüminyum alaşımlarından TM ile parça üretimi hakkında bilgi verilmiş,
özellikle mühendislik uygulamalarında sıklıkla kullanılan Al-Cu, Al-Si ve Al-Mg alaşımlarıyla ilgili
literatürdeki bir takım sonuçlardan örnekler sunulmuştur. Farklı alaşımların sinterlenmesi sonucu
elde edilen özellikler hakkında bilgi verilmiştir.
