  • The Effect of Accelerated Cooling on Microstructure and Impact Strength of
           S355J2 Quality Steels Used in Power Transmission Line Construction

    • Abstract: Publication date:  Jan 2019
      Source:Universal Journal of Materials Science  Volume  7  Number  1  Huseyin Zengin   Hayrettin Ahlatci   Serafettin Oner   Mustafa Emre Demirkazik   Sait Ozcelik   Yunus Turen   and Yavuz Sun   Heat treatment is the most commonly used production step which can change the overall mechanical properties of the material without changing the chemical composition. Among the heat treatment methods, accelerated cooling has been regarded as one of the most important method for obtaining good mechanical properties. Today, this method is used in the manufacture of thin pearlitic steel, double phase steel, bainitic steel in the production process of many different quality and size products from construction bar to profile. In the scope of this study, investigations were carried out on S355J2 equal angles section profiles produced by hot rolling method. It was observed that intensive inclusions were found in all of the materials and the mechanical strength could not be met at low rolling ratios. Particularly, these materials with low impact resistance have been subjected to accelerated cooling process in order to increase their impact strength. As a result of the accelerated cooling process, significant increases in impact strength have been observed, particularly with the change of microstructure.

  • Optical Properties of Lead Doped Titanium Oxide of Thin Films Prepared by
           Sol-Gel Method at Low Temperature

    • Abstract: Publication date:  Apr 2019
      Source:Universal Journal of Materials Science  Volume  7  Number  2  Fouzia. Abbas   and R. Bensaha   The present paper reports on the structural and optical properties of undoped and 5% Pb-doped TiO2 thin films deposited on glass and silicon substrates prepared by the sol-gel technique have been investigated. Dip-coated thin films have been examined at different annealing temperatures (400-500℃). The results shows that Pb-doped TiO2thin films start to crystallize at low temperature (400℃). The morphology and surface structure of the films were studied by scanning electron microscopy (SEM) and atomic force microscopy (AFM) reveals a nanoporous structure of anatase and brookite with particle sizes ranging between 20 nm and 100 nm. Refractive index and porosity were calculated from the measured transmittance spectrum. SE study permits to determine the annealing temperature effect on the optical properties and the optical gap of the Pb-doped TiO2 thin films. Photoluminescence (PL) spectrum revealed that emission increase with annealing temperature. A slight shift of transmission curves to higher wavelengths is observed for curves of Pb-doped TiO2 thin films in comparison with those undoped, this was explained by the lowering of the band gap of TiO2.

  • Optimization of Manufacturing of Operational Amplifier Manufactured by
           Using Field-effect Heterotransistor to Decrease Their Dimensions

    • Abstract: Publication date:  Apr 2019
      Source:Universal Journal of Materials Science  Volume  7  Number  2  E. L. Pankratov   In this paper we introduce an approach to decrease dimensions of operational amplifier based on field-effect heterotransistors. Dimensions of the elements will be decreased due to manufacture heterostructure with specific structure, doping of required areas of the heterostruc-ture by diffusion or ion implantation and optimization of annealing of dopant and/or radiation defects.

  • Double Interfacial Layers Effect on Optical Third-order Nonlinear
           Susceptibility, Refraction Index, and Absorption Coefficient of a Metal/
           Dielectric Composite

    • Abstract: Publication date:  Apr 2019
      Source:Universal Journal of Materials Science  Volume  7  Number  2  Berhanu Aragie   We investigate the way of enhancing the optical third order susceptibility, the refractive index, and absorption coefficient of a composite media in which identical nonlinear nanospheres having double interfacial layer randomly embedded in the linear host medium. We observe two maxima peaks of the nonlinear properties. We also show that the effect of double interfacial layers on the third order susceptibility, the refractive index, and absorption coefficient depends on the volume fraction metal/ dielectric nanosphers and the nature of the double interfacial layers. Under appropriate condition (nature of the two interfacial layer) we found two maximum peaks of the nonlinear properties. We also compare with the same composite without interfacial layer and in the presence of single interfacial layer and our finding shows that because of additional interfacial layer the effective medium exhibit a better third-order susceptibility, refractive index, and absorption coefficient.
