Abstract
In this paper the influence of different parameters on equal channel angular pressing (EADAP) of titanium alloy is investigated. In the first step the most important parameters are selected, and then a table of experiments is designed using Taguchi method. After designing the table of experiments, all of the experiments are simulated using Abacus software and the results are optimized using Taguchi method. The results shows that the optimum levels for ECAP method between the implemented experiments of titanium are 120 degrees for die channel, ambient temperature and 2 passes.
