摘要： A method includes the round billet skelping, several runs of each round billet drawing up to a given size, packing the drawn billets into a multilayer bank, corrugating the bank with the bellows formation as a result and its heat treatment. Each round billet is skelped of the age-hardenable nickel alloy containing components of the following group: niobium, aluminum, titanium, tungsten and molybdenum. Each round billet is drawn, heated up to the temperature of 1000-1130° C., held in the shielding medium at the above temperature, and cooled down, after that the above operations of drawing, heating, holding and cooling are repeated until the given size of each round billet is reached. The drawn round billets are packed into the multilayer bank and the bank is corrugated for forming the multilayer bellows. The heat treatment of the bellows is made by its heating up to the temperature of 1000-1130° C., holding in the shielding medium at this temperature until the strengthening phase is completely dissolved in the alloy and subsequent cooling down to the temperature of the phase transition termination in the alloy. A rarefied air medium or argon are used as the shielding medium.
