EXPERIMENTAL STUDY OFULTRASONIC WAVE EFFECTS ONMECHANICAL PROPERTIES OFMATERIALS

in this paper the effect of ultrasonic waveon the mechanical properties of materials is investi-gated by experiment. A new set of experiment sys-tem is developed, for purple copper and low carbonsteel specimens, respectively. Changes of materialsproperties and experimental result under an ultrasonic action are presented, soften mechanism is alsodiscused briefly
