FARKLI MATRİS KOMPOZİSYONLARI VE TAKVİYE ORANLARI İÇİN ALÜMİNYUM ESASLI KOMPOZİTLERİN TOZ METALURJİSİ YÖNTEMİYLE ÜRETİMİ VE KARAKTERİZASYONU
Abstract
In this study, effect of the different matrix composition and amounth of the boron carbide (B4C) reinforcment on the microstructure, mikrohardness and theoretical density were examined at aluminum based composites produced by powder metallurgy (P/M) method. For this purpose, three different matrix compositions (Al5Cu, Al5Mg and Al2.5Cu.2.Mg) and four different amount of the B4C by weight (% 5, 10, 20 and 30) were used. In addition to this, in order to investigate the effect of the production conditions, two different pressure (200 and 400 MPa) and three different sintering periods (60, 120 and 240 min.) were used. The theoretical density and microhardness of the produced aluminum based composites were measured and microstructure characterization was achieved via optic microscope
