Yaygın olarak kullanılan karbür parçacıkları göz önüne alındığında, titanyum karbür (TiC), sahip olduğu üstün fiziksel, mekanik özellikleri ve özellikle alüminyum ile uygun ara yüzey bağlanma yeteneğine sahip olması nedeniyle sıkça tercih edilen bir takviye malzemesi olarak kabul edilir. Bu çalışmada, ağırlıkça 3% nano titanyum karbür parçacıkları (nTiC) ile takviyelendirilmiş AA7075 alaşım matrisli kompozit malzemeler, bilyeli öğütme ve ardından sıcak presleme yoluyla başarıyla üretilmiştir. Öğütme süresinin (15 dk., 2 ve 10 sa.) tozların morfolojisi ve kristalografik özellikleri üzerindeki etkisi taramalı elektron mikroskobu, parçacık boyutu analizi ve X-ışını kırınımı ile karakterize edilmiştir. Öğütülmüş tozların konsolidasyonu 30 dakika boyunca uygulanan 400 MPa basınç ve 430 oC sıcaklık değerlerinde sıcak presleme yöntemi ile sağlanmıştır. Ayrıca, öğütme süresinin n-TiC/AA7075 kompozitlerinin mikro yapıları ve mekanik özellikleri üzerindeki etkisi, optik mikroskop ve sertlik sonuçları ile değerlendirilmiştir. Sonuçlar, aşırı plastik deformasyon sonucu sertleşen nano parçacıkların artan öğütme süresiyle matris içerisinde homojen olarak dağılması nedeniyle başlangıç AA7075 alaşım malzemesine kıyasla üç kat daha fazla sertlik değerlerine ulaşıldığını ortaya koymuştur.

The Effect of Mechanical Alloying Time on the Hardness of AA7075 Matrix Nanocomposite Materials Produced via Powder Metallurgy

Öz

Considering commonly used carbide particles, titanium carbide (TiC) is frequently preferred reinforcement material due to its superior physical, mechanical properties and especially its good bonding ability with aluminum. In this study, 3 wt.% nano titanium carbide particles (n-TiC) reinforced with AA7075 alloy matrix were successfully produced by a high energy planetary ball milling followed via hot pressing process. The effect of milling time (15 minutes, 2 hours, and 10 hours) on the morphology and crystallographic properties of the milled powders was characterized by scanning electron microscopy, particle size analysis and X-ray diffraction. The consolidation of the milled powders was achieved by hot pressing method under 400 MPa pressure and 430 oC temperature for 30 minutes. In addition, the effect of milling time on microstructure and mechanical properties of n-TiC/AA7075 composites was evaluated by optical microscope and hardness results. The results showed that three times the hardness values were accomplished compared to the initial AA7075 alloy material. The reason for this is that the nanoparticles which are hardened because of excessive plastic deformation were homogeneously distributed in the matrix with prolonging milling time.
