Simulation based on the Taylor model showed that the texture evolution during DCAP was very similar to that of ECAP up to the region, a so-called 'zero dilatation line'. Beyond this line, the texture continued to evolve by rotating about the transverse direction (TD) by 10-15 degrees during ECAP. whereas the texture hardly evolved during DCAP. These analytical observations were verified experimentally.
