Ultra-high frequency induction and conventional sintering of Al-SiO₂ composites: A comparative study

Abstract

In this study, it was aimed to determine and compare the sinterability of aluminum-SiO2 composites by conventional and fast sintering methods and to examine their tribological properties after the sintering process. For this purpose, 1, 3, 5, 9, and 15 wt.-% SiO2 reinforced aluminum matrix composites were sintered by a conventional and induction sintering method at 600 °C after uniaxial cold pressing under 200 MPa pressure. The sintering was performed for 30 minutes for the traditional method and 5 minutes for induction sintering. After the sintering, the microstructures of the samples were examined, and their sintered densities and hardness were determined. In addition, the tribological properties of the samples were investigated by the pin-on-disc method, and the worn surfaces were examined after the tests.

The impact of Cu, Ni and Fe2O3 on the magnetic behavior and structural properties of FeSiO2 nanocomposite synthesized through ball milling

“…Numerous research studies have been conducted by scientific researchers, focusing on the reinforcement of the SiO 2 matrix with diverse particles, including Fe, FeNi, FeCo, Fe 2 O 3 , Cu, Ni, Al, Co, CuCu 2 O, NiCoSiO 2 , FeCu, and NiMn. These investigations span various applications across multiple fields, with the goal of enhancing both physical and magnetic properties [8][9][10][11][12][13][14][15][16][17]. One of the attractive properties of iron particles incorporated in different matrix materials is that they present significant effective uniaxial anisotropy, despite their crystalline cubic symmetry [18,19].…”
