Computer controlled hammer (CCH) forging results in a reproducible, pre-programmed hammer blow energy and blow sequence, and a record of the actual velocity, energy and operation timing for each forged component. This new capability in hammer forging allows for sophisticated hammer forging processes executed under accurate control. At the same time, it also makes the process and microstructure modeling of hammer forging possible. In this study, hammer forging of Alloy 71 8 was performed run using a computer controlled hammer, and the microstructure and properties of the forged disks were evaluated. The process and microstructure modeling of the hammer forging was performed and correlated with experimental results. The results indicate that hammer forging can be run under accurate control and produce disks with high quality of microstructures and properties. This research also shows process and microstructure modeling of hammer forging is a powerful tool for the process development of high quality Alloy 71 8 components.
