Quantitative comparison between precision closed-die forging-force data and computer simulations
Article Abstract:
The reliability of computer models and precision closed-die experiments to accurately investigate the behavior of forged materials are evaluated. In the experimental setup, a universal testing machine is employed to forge a 63Sn/37Pb alloy specimen into an H-shaped structure. The structure is subsequently subjected to a series of axial load tests. The ALPID computer model is then used to simulate the same process. Results show a wide discrepancy between the simulated and experimental data. This is attributed to the inaccuracy of the power law used in the study.

Thermo-mechanical modeling of hot forging process
Article Abstract:
A study is conducted that uses a mathematical model to evaluate temperature and strain fields as well as dynamic and static microstructural changes during the ninisothermal forging process. Theoretical predictions for loadstroke behavior and austenite grain size are compared with experimental results for two grades of steel for verifying the results.
