FEM simulation of quenching process in A357 aluminum alloy cylindrical bars and reduction of quench residual stress through cold stretching process

- A FEM model for predicting residual stress of quenched cylindrical bars was created.
- A FEM model for residual stress reduction of quenched cylindrical bars was created.
- Heat transfer coefficient of water were accurately calculated.
- Proper quenching water temperature and cold stretching parameters were selected.
- Effect of aspect ratio of cylindrical bar on residual stress reduction was studied.
