METHOD OF METAL RECRYSTALLIZATION Russian patent published in 1996 - IPC

Abstract RU 2064510 C1

FIELD: metallurgy, methods of metals treatment to change their fine structure and physical and mechanical properties. SUBSTANCE: method allows to change metal properties due to realization of its recrystallization under action of electromagnetic field. method of metal recrystallization is exercised by pulsed electromagnetic field action on metal. Used electromagnetic field has intensity of 2• 105 ... 8• 106 A/m with frequency of 700 ... 800 Hz an pulse duration of 3/4π - 5/34p of frequency duration. EFFECT: method allows to exclude operation of recrystallization annealing.
