Abstract

Pancake forging of Inconel 718 was performed using a hydraulic press at temperature of 1273 and 1323 K. The effect of forging temperature on the microstructure of the pancakes was studied using optical microscopy. Variation in the microstructure was observed at different locations of the pancakes with fully recrystallized grains, partially recrystallized grains and necklace structure. Strain, strain rate and temperature across the pancake were determined through FEM analysis, and Johnson–Mehl–Avrami–Kolmogorov (JMAK) type model was employed to estimate the recrystallized grain size and volume fraction. There was close match between the predicted values and actual measurements.
