Synthesis and Characterization of MoSi2 Particle Reinforced AlCuMg Composites by Molten Salt Shielded Method

Öz:
AlCuMg and its alloys are the most preferred composite materials in areas such as automotive, aerospace and aerospace industries due to their positive properties such as high corrosive properties, heat resistance, high strength and toughness. However, the inadequacy of these alloys in terms of wear and mechanical properties is one of the problems encountered in the industry. As a result of the literature review, it has been determined that there are almost no studies to improve the mechanical properties of these alloys. In this study, MoSi2 particles in different percentages were added to AlCuMg matrix and produced by powder metallurgy method. The aim is to improve the mechanical properties of AlCuMg matrix composite material and to perform characterization processes. Molten salt shielded synthesis/sintering process was used as a protective atmosphere environment for the produced samples to protect them from oxidation during sintering. In salt-protected synthesis, potassium bromide (KBr) was preferred as the salt. After the synthesis process, Scanning Electron Microscope (SEM), Energy Dispersion Spectroscopy (EDS), X-Ray Diffractometry (XRD) analyzes were applied respectively as characterization processes. In addition, microhardness test was performed to determine the mechanical properties of the produced composites. It has been determined that MoSi2 particles reinforced to AlCuMg alloy increase the mechanical properties of AlCuMg composite material because they have high values in terms of hardness and melting temperature.

MoSi2 Parçacık Takviyeli AlCuMg Kompozitlerin Erimiş Tuz Korumalı Yöntem ile Sentezi ve Karakterizasyonu

Öz:
AlCuMg ve alaşımları yüksek korozif özellikleri, ısıl direnci, yüksek mukavemet ve tokluk gibi pozitif özelliklerinden dolayı otomotiv, havacılık ve uzay endüstrisi gibi alanlarda en çok tercih edilen kompozit malzemeler olarak karşımıza çıkmaktadır. Ancak, bu alaşımların aşınma ve mekanik özellik bakımından yetersiz olmaları endüstride karşılaşılan problemlerden biridir. Literatür taraması sonucunda bu alaşımların mekanik özelliklerini iyileştirmeye yönelik neredeyse yok denecek kadar az çalışmaların mevcut olduğu tespit edilmiştir. Bu çalışmada AlCuMg matrisine farklı yüzde oranlarında MoSi2 parçacıkları takviye edilerek toz metalurjisi yöntemi ile üretilmiştir. Amaç, AlCuMg matrisli kompozit malzemenin mekanik özelliklerini iyileştirerek karakterizasyon işlemlerinin yapılmasıdır. Üretilen numuneler için koruyucu atmosfer ortamı olarak, sinterleme esnasında oksidasyondan korumak için erimiş tuz korumalı sentez/sinterleme (molten salt shielded synthesis/sintering process) işlemi uygulanmıştır. Tuz korumalı sentez uygulamasında tuz olarak potasyum bromür (KBr) tercih edilmiştir. Sentezleme işlemi sonrasında karakterizasyon işlemleri olarak sırasıyla, Taramalı Elektron Mikroskobu (SEM), Enerji Dağılım Spektroskopisi (EDS), X-Işını Difraktometresi (XRD) analizleri uygulanmıştır. Buna ek olarak, üretilen kompozitlerin mekanik özelliklerini belirlemek için mikrosertlik testi yapılmıştır. AlCuMg alaşımına takviye edilen MoSi2 parçacıkları, sertlik ve ergime sıcaklığı olarak yüksek değerlere sahip olduğu için AlCuMg kompozit malzemesinin mekanik özelliklerini arttırdığı tespit edilmiştir. Takviyesiz olan numunenin sertliği yaklaşık 90 HV0,1’tir. % 5, 10 ve 15 MoSi2 ilavesine göre numunelerin sertliği sırasıyla 266, 317 ve 422 HV0,1’tir. MoSi2 katkılı numunelerin sertliği, takviyesiz üretilen numuneden daha yüksek çıkmıştır.
