METHOD TO TREAT ITEMS OF METALS AND ALLOYS Russian patent published in 1994 - IPC

Abstract RU 2025505 C1

FIELD: metallurgy, treatment of metals and alloys. SUBSTANCE: source of high energy density is used to heat an item surface concurrently with imposition of ultrasonic. Laser beam may be used as the source to heat it up to the temperatures not exceeding Ac₁, and then the item is cooled. Specific stress state is formed in the zone of combined influence. The stress state enables to speed up all processes needing thermal activation for its development. EFFECT: improved properties of metals and alloys.
