Metal matrix composites, which have low density, high hardness, good wear resistance and high specific strength properties, are an important type of advanced engineering materials and they are preferred especially in the automotive, defense and aerospace sectors due to these properties. Aluminum metal matrix composites constitute an important class of metal matrix composites with their features such as low density, cheapness and easy production. The main element that improves the mechanical properties of metal matrix composites such as strength and hardness and high temperature resistance is ceramic-based reinforcing elements. At this point, the selection of reinforcement materials is very critical. In this study, the Analytical Hierarchy Process (AHP) Method, which is one of the multi-criteria decision-making methods, is used to decide on the choice of reinforcement material. Rigidity, density, fracture toughness, price and melting point are chosen as selection criteria. B4C, TiC, SiC and Al2O3, which are the most preferred reinforcement materials in the production of metal matrix composites, are chosen as alternative reinforcement types. As a result of the study, it has been determined that the most important selection criterion is rigidity (51%) and the most suitable alternative reinforcement material is B4C (42%).

Öz

Düşük yoğunluk, yüksek sertlik, iyi aşınma direnci ve yüksek özgül mukavemet özelliklerine sahip olan Metal matris kompozitler ileri mühendislik malzemelerinin önemli bir türüdür ve bu özelliklerinden dolayı özellikle otomotiv, savunma, havacılık sektörlerinde tercih edilmektedirler. Alüminyum metal matris kompozitler düşük yoğunluk, ucuzluk ve kolay üretim gibi özellikleri ile metal matrisli kompozitlerin önemli bir sınıfını oluşturmaktadır. Metal matris kompozitlerin mukavemet ve sertlik gibi mekanik özelliklerini ve yüksek sıcaklık dayanımını geliştiren ana unsur seramik esaslı takviye elemanlarıdır. Bu noktada takviye malzemelerinin seçimi oldukça kritiktir. Bu çalışmada takviye malzemesi seçimine karar vermek amacıyla çok kriterli karar verme yöntemlerinden biri olan Analitik Hiyerarşi Prosesi (AHP) Yöntemi kullanılmıştır. Seçim kriterleri olarak rijitlik, yoğunluk, kırılma tokluğu, fiyat ve ergime noktası seçilmiştir. Metal matrisli kompozitlerin üretiminde en çok tercih edilen takviye malzemeleri olan B4C, TiC, SiC ve Al2O3 alternatif takviye türü olarak seçilmiştir. Yapılan çalışma sonucunda en önemli seçim kriterinin rijitlik (%51), en uygun alternatif takviye malzemesinin ise B4C (%42) olduğu belirlenmiştir.
