Abstract

B4C takviyeli Magnezyum matrisli
kompozit malzemelerden beklenen yüksek sertlik, aşınma direnci ve rijitlik
özelliklerinin elde edilebilmesi için B4C ile sıvı magnezyum
arasındaki ıslatma sorununun giderilmesi çok önemlidir. Bu çalışmada, % 5 ve
%10 B4C ile takviye edilmiş magnezyum matrisli (AZ91) kompozit
malzemeler 7500C'de karıştırma döküm yöntemi kullanılarak
üretilmiştir.  Üretilen kompozitlerin
mikroyapı ve matris/takviye arayüzleri Tarama Elektron Mikroskobu (SEM)
kullanılarak, matris/takviye arasındaki reaksiyon tabakası EDS analizi ve
X-ışını haritalaması ile karakterize edilmiştir. Yüksek çözünürlüğe sahip FEG-SEM
ile yapılan mikroyapısal inceleme sonucunda, arayüzeyde oluşan ince tabakanın
Mn-C ve Al-B bileşiklerinden oluştuğu 
belirlenmiştir.

Microstructural Variations In Cast B4C-Reinforced Magnesium Matrix Composites

Abstract

It is very important to
overcome the wetting problem between B4C and liquid magnesium so
that the high hardness, wear resistance and stiffness properties expected from
B4C reinforced Mg matrix composite materials can be obtained. In the
present work, Magnesiıum matrix (AZ91) composites reinforced with 5 and
10%(wt.) B4CP were produced by using stir casting method
at 7500C. Microstructure and matrix/reinforcement interfaces of
produced composites were have been characterized using scanning electron
microscopy (SEM) studies. The reaction layer between matrix/reinforcement was
also characterized with EDS analysis and X-ray mapping. It was found from the
microstructural observations by high resolution field emission gun SEM
(FEG-SEM) that the wetting improved by the formation of very thin Mn-C and Al-B
reaction layers.
