Abstract

In the work developed in this paper, the model of the microstructural behaviour of Inconel 718 for the rotary forging process is studied. This process is presented as an alternative to the conventional forging. The window process of Inconel 718 is very narrow, so the requirements for manufacturing Inconel are very restrictive. Optimisation of the rotary forging process was carried out in order to manufacture Inconel parts with good microstructural distribution. Microstructural specification was given by aeronautic sector. Numerical work was done in order to simulate the microstructural behaviour during the forming process. This method was used: a) to understand the recrystallization mechanism that take place in rotary forging processes and b) to study the influence of the initial grain size in the final part.
