Abstract

Bu
çalışmada, eş kalıp ekstrüzyon yöntemi ile boyutu milimetre aralığında değişen
ticari kalitede saf magnezyum talaşını takviye elemanı olarak kullanarak
alüminyum/magnezyum makrokompozit üretilmiştir. Kompozit karışımı 400 °C’de 9:1
ekstrüzyon oranında ektrüzyon işlemine tabi tutulmuştur. Makrokompozitin
karakterizasyonu mikroyapısal inceleme, yoğunluk ve sertlik ölçümleri ile
gerçekleştirilmiştir. Karakterizasyon sonucunda alüminyum alaşımı ve magnezyum
talaşı arasında yapısal bütünlüğün sağlandığı ve magnezyum talaşının katı halde
geri kazanılabileceği tespit edilmiştir.

Manufacturing and characterization of aluminium-magnesium macrocomposite by co-extrusion

Abstract

In
this study, aluminum-magnesium macrocomposite containing millimetre scale pure magnesium
chips reinforcement was fabricated. The composite was extruded at 400 °C with
an extrusion ratio of 9:1. Characterization of the macrocomposites was carried
out by microscopic examinations, density and hardness measurements. This work
demonstrated that not only the structural integrity between aluminum alloy and magnesium
chips but also the possibility of the solid state recycling of magnesium chips
can be provided.

Keywords
