AB  - B4C takviyeli Magnezyum matrislikompozit malzemelerden beklenen yüksek sertlik, aşınma direnci ve rijitliközelliklerinin elde edilebilmesi için B4C ile sıvı magnezyumarasındaki ıslatma sorununun giderilmesi çok önemlidir. Bu çalışmada, % 5 ve%10 B4C ile takviye edilmiş magnezyum matrisli (AZ91) kompozitmalzemeler 7500C'de karıştırma döküm yöntemi kullanılaraküretilmiştir. Üretilen kompozitlerinmikroyapı ve matris/takviye arayüzleri Tarama Elektron Mikroskobu (SEM)kullanılarak, matris/takviye arasındaki reaksiyon tabakası EDS analizi veX-ışını haritalaması ile karakterize edilmiştir. Yüksek çözünürlüğe sahip FEG-SEMile yapılan mikroyapısal inceleme sonucunda, arayüzeyde oluşan ince tabakanınMn-C ve Al-B bileşiklerinden oluştuğubelirlenmiştir.

N2  - It is very important toovercome the wetting problem between B4C and liquid magnesium sothat the high hardness, wear resistance and stiffness properties expected fromB4C reinforced Mg matrix composite materials can be obtained. In thepresent work, Magnesiıum matrix (AZ91) composites reinforced with 5 and10%(wt.) B4CP were produced by using stir casting methodat 7500C. Microstructure and matrix/reinforcement interfaces ofproduced composites were have been characterized using scanning electronmicroscopy (SEM) studies. The reaction layer between matrix/reinforcement wasalso characterized with EDS analysis and X-ray mapping. It was found from themicrostructural observations by high resolution field emission gun SEM(FEG-SEM) that the wetting improved by the formation of very thin Mn-C and Al-Breaction layers.
