Özet
In this study, iron and boron powders were alloyed at different rates (according to their molar weights) in a spex-type grinding device, and FeB and Fe2B compounds were obtained by mechanochemical method (the solid phase reaction). The containment and precise measurements of iron and boron mixed in different mole ratios were carried out with the Glove-Box in an argon atmosphere. Thermogravimetric and Differential Thermal Analysis for the determination of the sintering temperature of alloys; X-ray Diffraction and Scanning Electron Microscopy analyzes were performed to examine the phase compositions and microstructures. As a result of the studies, highly amorphous Fe2B and FeB compounds were produced. Due to the stoichiometric coefficients, the peaks of the FeB composition were more pronounced. For the sample targeted as FeB, it was observed that the peaks of the FeB composition were more pronounced due to the stoichiometric coefficients. From the EDS analysis, it was understood that the iron and boron elements on the surface of the samples exhibited a homogeneous distribution in the structure. According to the hardness results, it is understood that the sample targeted as FeB is harder than the samples targeted as Fe2B. This study will contribute to the production of advanced materials with regional hardness regimes by synthesizing different compositions.
