Bu çalışmada, ağırlıkça farklı oranlarda (%1, 3, 6, 9, 12, 15) alümina (Al2O3) içeren Al7075 alüminyum matrisli kompozitlerin üretimi ve karakterizasyonu gerçekleştirilmiştir. Toz metalürjisi ve indüksiyonla sıcak presleme yöntemleriyle üretilen numunelerin mikroyapısı, yoğunluğu, gözeneklilik oranı, sertliği ve basma dayanımı incelenmiştir. Çalışma sonucunda artan alümina takviyesinin belli bir orana kadar (ağırlıkça %12) kompozitin mekanik özelliklerini arttırdığı görülmüştür. En yüksek yoğunluğa (2.7 g cm-3), sertliğe (170±2 HV), basma dayanımına (471±6 MPa) ve en düşük gözeneklilik oranına (%8.2) Al7075-%12Al2O3 kompozitte erişilmiştir. Ancak ağırlıkça %15 alümina takviye oranında alümina partiküllerinin topaklanmasından kaynaklı olarak mekanik özeliklerde düşüş görülmüştür.

Investigation of the Mechanical Properties and Fabrication of Al7075-Al2O3 Composites by Powder Metallurgy and Hot Pressing

Öz

In this work, the fabrication and characterization of Al7075 aluminum matrix composites with different weight ratios (1, 3, 6, 9, 12, 15wt.%) of alumina (Al2O3) contents were carried out. The microstructure, density, porosity rate, hardness, and compressive strength of the samples were examined which were fabricated via the powder metallurgy and induction hot pressing methods. As a result of the study, it was seen that an increase in alumina reinforcement positively affected the microstructure and mechanical properties of the composite up to a certain rate (12% by weight). The highest density (2.7 g cm-3), hardness (170±2 HV), compressive strength (471±6 MPa), and lowest porosity rate (8.2%) were achieved in the Al7075-12%Al2O3 composite. However, a decrease in mechanical properties was observed at 15wt.% alumina reinforcement due to the agglomeration of alumina particles.
