Equimolar FeCoCrNi high entropy alloy (HEA) was produced from industrial raw materials which were not pure and contain various impurity elements such as Al, Si and C by induction melting in order to investigate mechanical properties of the alloy. This alloy was casted into compressed steel mold that let us to produce mechanical test samples. XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy) were used for structural characterization of the samples. Brinell hardness test was applied for mechanical characterization of the alloy. In the result of the experiments, it was observed that besides FCC phases, Cr7C3 phases were present in the HEA. The average hardness value of the alloy was found as 313 HB.

Mechanical properties of plasma surface-modified calcium carbonate-polypropylene composites Akovali, G; Akman, MA (Wiley, 1997-02-01) Calcium carbonate was surface-modified by plasma-polymerized acetylene and the effect of surface modification on the mechanical properties of calcium carbonate-polypropylene composites was investigated. Two different plasma polymerization conditions were selected and applied. Chemical structures of plasma-polymerized acetylene products were identified. Mechanical and thermal properties of the composites prepared were evaluated and the effects of surface modification on the extent of adhesion of filler to th...
Mechanical and microstructural evaluations of hot formed titanium sheets by electrical resistance heating process Ozturk, Fahrettin; Ece, Remzi Ecmel; Polat, Naki; Koksal, Arif; Evis, Zafer; Polat, Aytekin (Elsevier BV, 2013-08-20) In this study, effect of temperature in the electrical resistance heating process on mechanical properties and microstructures of commercially pure titanium grade 2 (CP2) and Ti-6Al-4V (T64) alloy sheets was investigated. Sheets were successfully heated by the electric resistance heating process, and their mechanical properties and microstructures were evaluated. Ductilities of both materials were increased significantly after 400 degrees C. Results indicate that no significant change was observed in grain ...
Mechanical and optical properties of SiO2 thin films deposited on glass Simurka, Lukas; Ctvrtlik, Radim; Tomastik, Jan; Bektaş, Gence; Svoboda, Jan; Bange, Klaus (2018-09-01) The optical and mechanical properties of amorphous SiO2 films deposited on soda-lime silicate float glass by reactive RF magnetron sputtering at room temperature were investigated in dependence of the process pressure. The densities of the films are strongly influenced by the process pressure and vary between 2.38 and 1.91 g cm(-3) as the pressure changes from 0.27 to 1.33 Pa. The refractive indices of the films shift between 1.52 and 1.37, while the residual compressive stresses in the deposited films vary...
Thermal and mechanical properties of Cu-Au intermetallic alloys Kart, HH; Tomak, Mehmet; Cagin, T (IOP Publishing, 2005-07-01) The thermal and mechanical properties of Cu, Au pure metals and their ordered intermetallic alloys of Cu3Au(L1(2)), CuAu(L1(0)) and CuAu3(L1(2)) are studied by using the molecular dynamics simulation. The effects of temperature and concentration on the physical properties of CuxAu1-x, are analysed. Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) many-body potentials are used. The simulation results such as cohesive energy, density, elastic constants, bulk modulus, heat capacity, thermal expansion, melting p...
Thermal degradation of polysiloxane and polyetherester containing benzoxazine moieties in the main chain Bagherifam, Shahla; Kışkan, Barış; Aydogan, Binnur; Yagci, Yusuf; Hacaloğlu, Jale (2011-01-01) In this study investigation of thermal characteristics of polysiloxane and polyetherester containing benzoxazine moieties in the main chain was performed via pyrolysis mass spectrometry. Pyrolysis mass spectrometry analyses revealed that the thermal stability and the extent of cross-linking enhanced when the benzoxazine moieties were separated by thermally more stable units such as siloxanes. However, when the siloxane chain units were long, possibility of polybenzoxazine growth decreased significantly and ...
