    • Two-Way Shape memory Effect in a Cu-13wt. %Al-4 wt.%Ni Shape Memory alloy by the Thermo-Mechanical Cycling Method 

      Gurău, Carmela; Gurău, Gheorghe; Alexandru, Petrică (Universitatea "Dunărea de Jos" din Galați, 2007)
      A Cu - 13 % wt Al 4% wt Ni polycrystalline shape memory alloy has studied with a thermo mechanical cycling method. The two – way shape memory effect (TWSME) was obtained bending the alloy around a cylinder mold and by ...

    • Values of the Solutal Marangoni Number in Very Dilute Fe-C-O Solutions at 1873K 

      Niță, Petre Stelian (Universitatea "Dunărea de Jos" din Galați, 2007)
      Low carbon, aluminum killed steels are well represented by the adequate part of the Fe-C-O system, where are available useful experimental data, regarding the surface tension and viscosity. The reference dynamic ...

    • Vibration Diagnosis Systems for a Cold Rolling Mill Machine 

      Dragomir, Ștefan; Măcuță, Silviu; Spânu, Constantin (Universitatea "Dunărea de Jos" din Galați, 2007)
      In this work is shown the importance to use a monitoring by vibration system for a cold rolling mill machine. The using of this monitoring vibration system reduce maintenance costs, minimize the impact on operation because ...

    • X-Ray Diffraction Residual Stress Measurements for Quality Control Testing 

      Gheorghieș, Constantin; Cantaragiu, Alina-Mihaela; Stasi, Iuliana Valentina (Universitatea "Dunărea de Jos" din Galați, 2007)
      This paper present the primary difficulties which are associated with the obtaining and interpreting surface X-ray diffraction residual stress results: the surface stresses may be identical for the shoot peening, nitriding ...
