    • Grain Refinement in Aluminum Alloys by Acoustic Cavitation Phenomena 

      Moraru, Luminița (Universitatea "Dunărea de Jos" din Galați, 2007)
      In this article, ultrasonic method of transmitting forced vibrations to solidifying aluminum-alloy melts is presented. In the presence of well developed cavitation situations, a fine and homogeneous microstructure has ...

    • Ultrasound Action on Strength Properties of Polycrystalline Metals 

      Moraru, Luminița (Universitatea ”Dunărea de Jos” din Galați, 2006)
      The mechanical properties of pure aluminum were investigated by tensile test on the sample with average grain size between 60 and 1000 µ m. The stress strain functions given by the models are fitted to the measured points. ...
