Abstract
The invention relates to a joining method for the production of a component from two or more constructional elements which are manufactured from a highly distortion-resistant metallic material, in particular a material based on nickel or iron. The constructional elements and the interlayer are manufactured from an oxide dispersion-hardened material, and are joined together with insertion of the interlayer to give the component. The interlayer is in an unrecrystallized fine-grained plastic state before the joining process, and undergoes recrystallization, as a result of heat treatment, only after the joining process, which is carried out at a temperature of 800 to 1,100 degrees centigrade and under a pressure of 1 to 200 Mpa.
