Abstract

See full text

A method for forging a niobium-tungsten alloy forged ring, including: (S1) subjecting an alloy ingot to turning, chamfering, spraying with an anti-oxidation coating, stainless-steel sheathing, heating and upsetting to obtain a primary pancake with a flat-die hammer, rapid-forging press or hydraulic press; (S2) subjecting an inner pole to wire electrical discharge machining to obtain a ring blank followed by machining to remove the stainless-steel sheath and oxide scale and defects; and subjecting the ring blank to fluorescent/dye penetrant inspection followed by vacuum stress-relief annealing; (S3) subjecting the ring blank to core shaft/saddle forging on the flat-die hammer or rapid-forging press to obtain a crude forged ring; and (S4) subjecting the crude forged ring to vacuum recrystallization annealing to obtain a desired forged ring.
