Performance of Superalloy Based on Fuzzy PID Control Algorithm

In the radial forging process of Inconel 718 superalloy, the initial forging temperature and final forging temperature were controlled by conventional PID control and fuzzy PID control, respectively, and the high temperature wear properties and high temperature oxidation properties of samples were tested and analyzed. The results show that compared with those of the conventional PID control, the wear volume of the alloy reduces by 42% after 700℃ high temperature wear for 25min, and the mass change per unit area reduces by 38% after oxidation at 700℃ for 20 h, which improves the high temperature wear properties and high temperature oxidation properties of the alloy samples.
