    Abstract:

    Nickel-based superalloys can be characterized by resistance to high-temperature corrosion and high-temperature creep resistance. For this reason, they are widely used in the production of jet engine critical parts. One of the commonly used materials is Inconel 625, which will be the subject of this research. For Inconel 625 processing, rotary forming can be applied, which results in axially symmetrical elements. An important property of Inconel 625 is strong strain hardening effect. To improve formability, variety of methods can be applied, including heating of the material. The purpose of the research was optimization of rotary forming process parameters of Inconel 625 to produce jet engine critical parts with high quality requirements. Experimental plans based on orthogonal two-level design was created for 3 selected variables - feed rate, spinning rate, and heating. Optimal process parameters were established using multivariate statistical optimization utilizing GridSearch algorithm for finding set of parameters maximizing general product quality, defined as function of several quality factors measures. These parameters were used to set up processes and obtain product that meet quality requirements.
