    • Composite-Decorative Tiles with Granite 

      Potecașu, Octavian; Potecașu, Florentina; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2006)
      The paper presents the results of the authors’ scientific research on a composite material with polymeric matrix, hardened with rock particles. It was studied the influence of the quantity of the hardening phase on the ...

    • Hardened Aluminum with Oxide Particles 

      Potecașu, Florentina; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2006)
      The paper presents the effect of size and dispersion degree of the particles of aluminum oxide, on structure, mechanical characteristics and phenomena that take place when heating at different temperatures for ...

    • 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, ...

    • The Assessing of Mechanical Characteristics of the Steel Sheets Designed for Drawing for a Five-Month-Period as an Effect of Natural Ageing 

      Potecașu, octavian; Potecașu, Florentina; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2009)
      In the paper it is presented a study run on a five-month-period regarding the changes in the mechanical characteristics due to natural ageing for a drawing steel, cold rolled, unalloyed with 0.04% C. The ageing tendency ...

    • The Properties of Hardened Lead 

      Potecașu, Florentina; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2005)
      Lead hardened through oxide scattering is investigated as raw materials for the fabrication of the support gratings of lead accumulators in order to increase their life service. For the preparation of lead powder hardened ...

    • Wear Behavior of Carburizing on Powder Metallurgy Alloys 

      Marin, Mihaela; Potecașu, Florentina; Alexandru, Petrică; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2014)
      In this paper is studied the influence of wear behavior of carburizing in fluidized-bed on sintered alloys produced by powder metallurgy route. In powder metallurgy, carburization is a thermochemically treatment that ...
