Equipotential lines were used to optimize the shape of a preform die for producing aluminum alloy (AA2017) turbine disks. The optimization criteria were complete filling, reduced forging loads and uniform effective plastic strain. Using the optimal preform die identified by the adopted optimization method, the maximum and minimum effective plastic strains were increased from 1.09 and 0.1562 to 1.429 and 0.218, respectively. Moreover, the required forging force was reduced from 3.12 to 2.58 E4 kN. This shows that the preform die reduced the maximum press capacity required to forge the disk. It also produced good results in terms of full filling and the absence of dead zones, which were evidenced by the die contact.
