Eş kalıp ekstrüzyon yöntemi ile alüminyum-magnezyum makrokompozit imalatı ve karakterizasyonu

Öz

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.
