Response of copper to Equal Channel Angular Pressing with different processing temperature

Structural property relationship indicates the significance of Ultra Fine Grain (UFG) for attainment of enhanced strength without any chemistry alteration. Ultra fine grain structure can be produced by Equal Channel Angular Pressing (ECAP) by proper selection of die geometry, route (method specimen rotation for each number passes) and processing temperature. The present study illustrates the significance of processing temperature on attainment of higher strength with ductility. Compared to room temperature, processing with 2000C, results in significant contribution of ECAP by way of structural-strengthening. However, both the processing indicates a critical value of 3, passes, for attaining the desired results.
