    Production and Characterization Of Ti-10Cr-3,33Co-3,33Egg Shelter Composite Materials Using By Powder Metallurgy
    (Kırıkkale Üniversitesi, 2020) Yönetken, Ahmet; Pesmen, Günnur; Erol, Ayhan
    Titanium-based intermetallic compoundsare frequently used in the production of biomaterials. The behavior of titaniumsimilar to bone mechanical properties causes the use of titanium as abiomaterial and preferred among the materials. It also makes its use attractivein industrial applications at high temperatures. TiCrCo intermetallics areknown to be used together with Ti matrix materials to improve the properties ofthe group in addition to elements such as Cr, especially Ti, Co, Mo and Fe invarious application areas. This information is used frequently in the sinteringprocess. In this study, Ti-10Cr-3,33Co-3,33 egg shelter powders were prepared as a sample mixture. When the properties of the samples produced after sintering are examined, it shows the effects of Co on TiCr. 3.33% Co additive was used in the composition of the composition and mechanical properties were determined in the produced samples. By looking at metallographic analysis, structural features were tried to be determined. The density of the produced samples was calculated, hardness and shear strength were determined. According to the results of the analysis, 3.33% Co composition and 3.71 gr / cm3 density, and 285.5 HV hardness values at 1200 ° C were obtained. In this study,Ti-10Cr-3,33Co-3,33 egg shelter powders were prepared as a sample mixture.

    Sintering and Characterization of SiC Reinforced Ni Powders in Microwave Furnace
    (Kırıkkale Üniversitesi, 2020) Yonetken, Ahmet; Erol, Ayhan
    SiC reinforced nickel matrix composites,microwave at different temperatures It is produced by sintering in oven. Nickeldeposition on SiC powders was achieved by using electroless nickel platingtechnique.  It is sintered at temperaturesbetween 500°C, 600 °C, 700°C, 800°C and 900°C under Ar atmosphere. XRD, SEM(Scanning Electron Microscope), pressure test and hardness measurements wereused to characterize the properties of sintered samples in microwave furnace. Theexperimental results, maximum compressive strength (?max) and hardness (HV)were carried out at 800 °C.  Microwavesintering of Ni-coated SiC powders without electric current can be a promisingtechnique for producing ceramic-reinforced nickel composites.
