    • Preliminary Results on the use of Palm Oil and Shea Butter in Lubrication Process in Food Industry 

      Bike Mbah, Jean Baptiste; Kamga, Richard; Gheorghieș, Constantin; Praisler, Mirela (Universitatea ”Dunărea de Jos” din Galați, 2009)
      In this study, vegetal oils (palm oil and shea butter) are analyzed for their uses in lubrication of mechanical part of machines in food industry. These vegetal oils were analyzed by X-ray diffraction and transmission ...

    • The temperature Effect on Severely Deformed Aluminium by High Pressure Torsion 

      Gurău, Carmela; Gurău, Gheorghe; Cănănău, Nicolae; Potecașu, Florentina; Dogaru, Victor; Fernandes, FM Braz (Universitatea "Dunărea de Jos" din Galați, 2009)
      The process of deforming materials started to attract the interest of the researchers after the development of the severe plastic deformation techniques. A number of aluminium samples were severe deformed by HPT method ...

    • 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 ...

    • XRD Analysis in Front of a Corrosion Crack Tip 

      Gheorghieș, C.; Levcovici, S.; Păunoiu, V.; Gheorgieș, L.; Oancea, C.; Ostache, I.; Alexandru, P. (Universitatea "Dunărea de Jos" din Galați, 2008)
      During exploitation of the heat exchangers some damages can appear in the contact region between the gaskets and the stainless steel walls. The studies upon the material were performed using SEM microscopy, X-ray ...
