METHOD FOR MAKING ARTICLES IN CONDITION OF RESONANCE OSCILLATION OF STRUCTURAL PARTICLES OF MATERIAL Russian patent published in 2005 - IPC

FIELD: manufacture of articles in condition of resonance oscillations of structural particles of material.

SUBSTANCE: method comprises steps of preparing metal and acting upon it by means of mechanical ultrasound frequency oscillations in order to achieve resonance. According to invention at extrusion or at rolling action by means of ultrasound frequency oscillations is realized at frequency values corresponding or proportional to natural frequency of oscillation of dispersed metal particles in order to provide density of article 0.92 -0.99 and more. At plastic working, at drawing or cutting action by means of ultrasound frequency oscillations is realized at frequency values corresponding or proportional to natural oscillation frequency of grain or domain of metal. At crystallization action by means of ultrasound frequency oscillation is realized at frequency values corresponding or proportional to natural frequency of crystallized grains of metal. During extrusion and rolling process of metal preparation comprises steps of washing out, breaking, metering; during crystallization process of metal preparation comprises steps of melting and casting metal to ingot mold or casting mold.

EFFECT: enhanced quality of articles, lowered cost, improved efficiency of production process.
