Production and Characterization of Animal Waste Reinforced Composite Materials By Powder Metallurgy

Abstract

Boron carbide is a product used for reinforcement in composite production and frequently used in the defense industry. The fact that boron carbide behaves similarly to the mechanical properties of bone and that titanium is strengthened with boron carbide, which is used as a biomaterial, causes it to be preferred among composite materials. It also makes it attractive to use in industrial applications at high temperatures. It is known that Fe-B4C composites are used together with Fe matrix materials to improve the properties of the group in addition to elements such as Cr, especially Ti, Co, Mo and Fe in various application areas. This makes it frequently used in the sintering process. In this study, 98,33%Fe-1,66%B4C, 96.66%Fe-1,66%B4C-1,66%eggshell powders, 95%Fe-1,66%B4C-3,32%eggshell powders, 93,33%Fe-1,66%B4C-5%eggshell powders and 91,66%Fe-1,66%B4C-6,66% eggshell powder samples were prepared using the compositions of. It is formed in a single axis press under 400bar pressure. When the mechanical and metallographic properties of the samples produced after sintering at 1400 ᵒC were examined, the effects of eggshell powders on composite samples produced by adding Fe-B4C composite and eggshell powders in different compositions were observed. 1,66% to 6,66% eggshell powders additive was used in the compositions and mechanical properties were determined in the produced samples. Structural features were tried to be determined by looking at metallographic analyses. The densities of the produced samples were calculated and their hardness and strength were determined. According to the analysis results, 3,33% Egshelters composition and 3,71 gr/cm3 density and 285,5 HV hardness values ​​at 1400 °C were obtained.

Effect of ball milling on hexagonal boron nitride (hBN) and development of Al-hBN nanocomposites by powder metallurgy route

“…Yonetken and Erol [18] fabricated Al-based composites reinforced with 3, 6, 9, 12, and 15% of BN by conventional microwave sintering at 550 • C. They reported the formation of compounds between the Al matrix and the BN reinforcement. Their study showed that the highest microhardness of 42.65 HV was observed in the case of Al at 12% BN, while the highest density of 2.975 g/cc was observed in the case of Al at 3% BN.…”

Investigation Of Mechanical Properties Of Nano Boron Nitride Added Aluminum Material Produced By Different Production Method

“…Bu özellikler alüminyumu nano BN ile güçlendirmek için önemli bir malzeme yapmaktadır [33]. Ayrıca nano BN takviyeli metal matrisli kompozitler; kıvılcım plazma sinterleme, sıcak haddeleme ve döküm gibi yüksek sıcaklık teknikleri kullanılarak üretilebilmektedir [34][35][36][37][38]. Nano BN incelendiğinde, hegzagonal BN'ın (h-BN) içyapısı [39] görülebilir.…”
