dc.description.abstract	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. The grain size dependence on the uniform yield stress was studied. In order to put in evidence the effect of ultrasonic field on grain size, the measurements were carried out for samples solidified under similar conditions both with and without sonication. For pure aluminium, the author quantitatively evaluated the validity of Hall-Petch model.	ro_RO
