Toz metalurji yöntemiyle üretilen MgO-ile takviyeli Al-Cu metal matriks kompozitlerinin mikroyapisal ve mekanik karakterizasyonu

Abstract

Seramik parçacıkları ile takviye edilmiş metal matriks kompozitleri (MMCs), takviye edilmemiş matrislere kıyasla artırılmış dayanım, aşınma direnci ve termal stabilite gibi üstün özellikler sunar. Bu çalışma, toz metalurjisi ile üretilen Al-Cu kompozitlerinin mikroyapısı, yoğunluğu ve sertliği üzerindeki değişen magnezyum oksit (MgO) içeriğinin etkilerini incelemektedir. MgO, %1, %3 ve %5 ağırlık oranlarında eklenmiş ve kompozitler, Vickers mikrosertlik testi, Arşimet Prensibi ile yoğunluk ölçümü ve mikroyapısal analizler gibi çeşitli yöntemlerle karakterize edilmiştir. Sonuçlar, MgO eklenmesinin kompozit yoğunluğunda hafif bir artışa yol açtığını, en yüksek sertlik değerlerinin ise %1 MgO içeren kompozitte gözlendiğini göstermektedir. MgO parçacıklarının varlığı, sert seramik parçacıkları ve intermetalik fazların oluşumu yoluyla plastik deformasyonu sınırlayarak sertliği artırmaktadır. Ayrıca, MgO’nun eklenmesi, muhtemelen çekirdeklenme ajanı olarak rol oynayarak tane yapısını iyileştirmiş ve bu da mekanik özelliklerin daha da gelişmesine katkı sağlamıştır. Bu çalışma, MgO’nun Al-Cu kompozitlerinin özelliklerini iyileştirmedeki rolüne dair değerli bilgiler sunmakta ve yüksek dayanıklı, hafif malzemelere ihtiyaç duyan sanayilerdeki potansiyel uygulamaları vurgulamaktadır.

Microstructural and mechanical characterization of MgO-reinforced Al-Cu metal matrix composites fabricated via powder metallurgy

Abstract

Metal matrix composites (MMCs) incorporating ceramic particulates exhibit enhanced mechanical properties, including increased tensile strength, wear resistance, and thermal stability, compared to their unreinforced counterparts. This research investigates how varying amounts of magnesium oxide (MgO) affect Al-Cu composites’ microstructure, porosity, and hardness produced through powder metallurgy. MgO was added in weight percentages of 1%, 3%, and 5%, and the composites were assessed using several methods, such as Vickers microhardness testing, Archimedean density measurement, and scanning electron microscopy for microstructural analysis. The findings indicate that incorporating MgO leads to a slight increase in composite density, with the highest hardness measured at 1% MgO. This increase in hardness is associated with the presence of rigid ceramic reinforcements and intermetallic compounds that resist plastic deformation. Additionally, MgO particles promote grain refinement, likely due to their nucleating effect, which further enhances mechanical properties. This research provides valuable insights into the role of MgO as a reinforcement in Al-Cu composites, underscoring its potential applications in industries that demand materials with high strength and low density.
