Latest Patents

Youqiang Liu holds a patent for a "Method for forging niobium-tungsten alloy forged ring." This method involves several key steps: first, the alloy ingot is subjected to turning, chamfering, and spraying with an anti-oxidation coating. It is then sheathed in stainless steel, heated, and upset to create a primary pancake using a flat-die hammer, rapid-forging press, or hydraulic press. The process continues with wire electrical discharge machining to obtain a ring blank, followed by machining to remove the stainless-steel sheath and oxide scale. The ring blank undergoes fluorescent/dye penetrant inspection and vacuum stress-relief annealing. Subsequently, it is subjected to core shaft/saddle forging to create a crude forged ring, which is finally processed through vacuum recrystallization annealing to achieve the desired forged ring.
