Özet:

 In this study, hybrid reinforced composites with Al6061 matrix and different wt. amounts TiC, SiC and B4C were produced by vacuum infiltration method. After dissolution at 540ºC for 3 hours, aging heat treatment was applied to the produced samples at 130ºC with 3-hour intervals for a total of 24 hours. FESEM, EDS and XRD analyzes were performed to evaluate the homogeneity and wettability of hybrid composites after production and heat treatment. When the analysis results were evaluated; reinforcements in the produced composites were homogeneously dispersed in the matrix. These reinforcements exhibited good wettability in the structures produced in a 520mmHg vacuum environment for 5 minutes at a melting temperature of 900ºC. In addition, microhardness measurements were made after the heat treatments. Depending on the aging temperature applied after dissolution, it was observed that the hardness increased up to 18 hours and decreased after 18 hours.

 Bu çalışmada, vakum infiltrasyon yöntemiyle Al6061 matrisli,  ağırlıkça farklı miktarlarda TiC, SiC ve B4C içeren hibrit takviyeli kompozitler üretilmiştir. Üretilen numunelere, 540ºC sıcaklıkta 3 saat çözündürme işlemi sonrasında 130ºC sıcaklıkta, 3er saat aralıklarla toplam 24 saat yaşlandırma ısıl işlemi uygulanmıştır. Üretim ve ısıl işlemlerden sonra hibrit kompozitlere homojenliğini ve ıslatılabilirliğini değerlendirmek için FESEM, EDS ve XRD analizleri yapılmıştır. Analiz sonuçları değerlendirildiğinde; üretilen kompozitlerdeki takviyeler matris içinde homojen olarak dağılmıştır. Bu takviyeler 900ºC ergitme sıcaklığında, 5 dakika süreyle 520mmHg vakum ortamında üretilen yapılarda iyi ıslatılabilirlik sergilemiştir. Ayrıca ısıl işlemlerden sonra mikro sertlik ölçümleri yapılmıştır. Çözündürme sonrası uygulanan yaşlandırma sıcaklığına bağlı olarak sertliğin 18 saate kadar arttığı, 18 saat süreden sonra ise düştüğü görülmüştür.
