Investigation of Microstructure, Microhardness and Thermal Properties of Ag-In Intermetallic Alloys Prepared by Vacuum Arc Meltings

引用

Journal of Wuhan University of Technology(Materials Science) 2024年第1期39卷 182-187页

作者： ÇELİK Erçevik ATA ESENER Pınar ÖZTÜrk Esra AKSÖZ Sezen Nevşehir HacıBektaşVeli University Department of Physics50300NevşehirTurkey Erciyes University Graduate School of Natural and Applied Sciences38039KayseriTurkey Kocaeli University Department of Physics41380KocaeliTurkey

Ag-In intermetallic alloys were produced by using vacuum arc furnace. Differential Scanning Calorimetry(DSC) and Energy Dispersive X-Ray Spectrometry(EDX) were used to determine the thermal properties and chemical composition of the phases respectively. Microhardness values of Ag-In intermetallics were calculated with Vickers hardness measurement method. According to the experimental results, Ag-34 wt%In intermetallic system generated the best results of energy saving and storage compared to other intermetallic systems. Also from the microhardness results, it was observed that intermetallic alloys were harder than pure silver and Ag-26 wt%In system had the highest microhardness value with 143.45 kg/mm^(2).

Alternative scattering kernels for the first estimates of a reactor:diffusion length

引用

Nuclear Science and Techniques 2018年第3期29卷 86-91页

作者： Hakan oztürk Ayca Simsek Yapar Department of Physics Faculty of Arts and SciencesOsmaniye Korkut Ata University80000 OsmaniyeTurkey

Diffusion-length calculations of neutrons are performed using the Chebyshev polynomials of the second kind. The neutrons are assumed to move with constant energy in a uniform homogeneous slab. An alternative scattering kernel called an Anl?–Gngr phase function and a traditional Henyey–Greenstein phase function are used for the scattering function in the stationary neutron transport equation. First, analytic expressions and then numerical results are obtained for the diffusion length for various values of the scattering and cross-sectional *** results obtained from both scattering kernels for the diffusion length of the neutrons are given in tables side by side for comparison. The applicability of the method is easily demonstrated by these results.

Effect of Annealing on Microstructure and Microhardness of Co-Fe-Ni-Ta-B-Si Bulk Metallic Glass

Journal of Materials Science & Technology 2015年第2期31卷 148-152页

作者： Aytekin Hitit Merve Gecgin Pelin oztürk Department of Materials Science and Engineering Afyon Kocatepe UniversityAfyonkarahisar 03200Turkey Department of Materials Science and Engineering Anadolu UniversityEskisehir 26555Turkey

Effects of annealing temperature and time on microstructure and microhardness of Co41Ni2Fe20Ta5.5B26.5Si5 amorphous alloy have been investigated. Microhardness of the as-cast alloy is found to be 1170 HV. The maximum microhardness,1798 HV,is achieved after annealing the amorphous alloy at 1250 K for 10 *** of the microstructure reveals that(Co,Fe)2B,(Co,Fe)21Ta2B6 and(Co,Fe)16Ta6Si7 phases precipitate in the matrix after annealing. Intrinsic hardness and Hall-Petch coefficients of the precipitates indicate that high hardness values result from precipitation of(Co,Fe)2B and(Co,Fe)21Ta2B6 phases. It is also observed that increasing the annealing time results in the decrease in microhardness values because of the increase in particle sizes of the precipitates.
