Abstract
The most recent and advanced technique for grain refinement, Equal Channel Angular Pressing, is used in bulk materials to enhance the mechanical and other properties of materials. The objective of the present study is to investigate the effect of various die design parameters and to obtain the optimum value of these parameters. The parameters used are channel angle, corner angle, number of passes, on the shear strain produced by the mathematical method and the results were compared using response surface methodology. It has been investigated that the optimum values for producing maximum shear strain are for 90° channel angle and 0° corner angle. The value of shear strain reduces with the increase in channel angle and corner angle both. The results obtained by mathematical equation and by RSM are in good agreement with each other. It is expected that the present study will be useful for sustainable manufacturing applications, especially in aerospace, automobile, defence, health and similar other sectors.
