Bu çalışmada bir Aşırı Plastik Deformasyon (Severe Plastic Deformation-SPD) yöntemi olan Çok Yönlü Dövme (Multi-Directional Forging ‘MDF’) işleminin AA5083 alüminyum alaşımına uygulanması deneysel olarak incelenmiştir. MDF işlemi, tavlama ısıl işlemi yapılarak homojenleştirilen numuneler üzerine oda koşullarında yaklaşık 25 °C sıcaklıkta 4 pasoya kadar uygulandı. MDF işleminde küp şeklindeki hazırlanmış numuneye sırasıyla üç eksen doğrultusunda yapılan presleme (dövme) işlemlerinin tamamı bir paso olarak kabul edilmektedir. MDF işlemleri sonrasında ise malzemenin mekanik özelliklerindeki değişim, sertlik ve basma testleri yardımı ile belirlendi. Yapılan bu testler neticesinde her bir MDF işleminin malzemenin sertlik ve basma dayanım özelliklerini artırdığı tespit edilmiştir. Bu çalışma benzer çalışmaların aksine oda koşullarında yapıldığı için aynı strain oranına karşılık uygulanan plastik deformasyon ile malzemede daha fazla mukavemet ve sertlik artışı gözlemlenmiştir. Bu çalışmada şekil değişimi oranı her presleme için % 10 olarak sabit alınmıştır.

In this study, the application of Multi-Directional Forging (MDF) process, which is a Severe Plastic Deformation-SPD method, to AA5083 aluminum alloy was experimentally investigated. MDF treatment was applied on the specimens at room conditions at approximately 25 °C for up to 4 passes that the specimens were homogenized by annealing heat treatment. In the MDF process, all of the pressing (forging) operations performed on the cube-shaped sample, respectively, in the direction of three axes, are considered as one pass. After the MDF processes, the change in the mechanical properties of the material was determined with the help of hardness and compression tests. As a result of these tests, it has been determined that each MDF process increases the hardness and compression strength properties of the material. Since this study was carried out in room conditions, unlike similar studies, more strength and hardness increases were observed in the material with the applied plastic deformation against the same strain rate. In this study, the strain rate was taken as 10% for each press.
