    • Intermetalic Copper Phase Characteristics and Links with the Gold Sphere in Alumina Cover Sheets 

      Benta, Marius Dan; Mogan, Petre Nicolae; Drăgușin, Georgiana (Universitatea "Dunărea de Jos" din Galați, 2007)
      The time period in which the intermetalic sheet cover is developed into the gold sphere in alumina is fully known being relatively not much literature regarding the morphology ant intermetalic phases growth in the copper ...

    • Behaviour at Nitriding in Fluidized Layer of Austenitic Stainless Steels at the Temperature 

      Dima, Ovidiu (Universitatea "Dunărea de Jos" din Galați, 2007)
      Nitriding at low temperatures, 450-500oC of austenic stainless steels lead to the obtaining of the tough layers over 1000 HV005 but having thicknesses of tenths of microns. Moreover, nitriding at 500ºC has determined the ...

    • Analysis of Steructural Components Exiting in Steel Making Slag Sampled from Steel Making-Continuous casting Flow Sheet 

      Preda, Adriana; Ivan, Ion; Zăman, Florin (Universitatea "Dunărea de Jos" din Galați, 2007)
      Hereby paper work aims to identify and analyze the structural constituents from the steel making shop slag. Therefore, slag specimens sampled from different stages of steel making-continuous casting flow sheet in Mittal ...

    • Multifunctional ZnO-Based thin Films by SOL-GEL Method 

      Mușat, Viorica; Fortunato, Elvira (Universitatea "Dunărea de Jos" din Galați, 2007)
      The paper presents the crystalline structure, morphology, optical transmittance, electrical properties and room temperature photoreduction-ozone oxidation properties of some Al-doped ZnO thin films prepared by sol-gel ...

    • Severe Plastic Deformation an Advanced Method for Nanostructuring Shape Memory Alloys 

      Gurău, Gheorghe; Gurău, Carmela; Tănase, Dinel; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2007)
      Severe plastic deformation (SPD) is an advanced plastic deformation. In this process nanostructuring metals and alloys may be produced. Nanostructured shape memory alloys are associate with a very high strength, toughness, ...

    • Manufacture of Stud Link Chain Cable Made of Grade U1 and U2 Steel 

      Drăgan, Viorel; Bordei, Marian; Chis, Chris Mircea (Universitatea "Dunărea de Jos" din Galați, 2007)
      We have analyzed the fabrication technology of the link chain cable made of grade U1 and U2 steel from TREFO S.A. Galati and we had in view during the experiments several rolling programs. The main characteristics of a ...

    • Study of the Thermodynamic Regime at the Continuous Casting of Steel 

      Ivănescu, Alexandru; Ivănescu, Lilica; Cireșica, Cocindau; Munteanu, Viorel (Universitatea "Dunărea de Jos" din Galați, 2007)
      The paper presents the evolution of the heat exchange coefficient along the path of the continuous casting unit, as a function of the cooling water flow rate and the path length. The optimization of this thermodynamic ...

    • Some Aspects About the Refractory Lining Wear in Furnaces 

      Bedő, Tibor (Universitatea "Dunărea de Jos' din Galați, 2007)
      For melting cast iron, carbon steel, copper and copper alloys the quartzite is still one of the most used lining material and the most cost effective as well. The silica lining has to be replaced frequently due to the ...
