jfet.13.1.13760 Importance of E-Cap Die Design for Producing Improved Hardness and Ultra Fine Grains of Aluminum Alloy-6xxx Series Sunil Kadiyan Brijnandan Singh Dehiya Journal on Future Engineering and Technology 2230–7184 13 1 30 35 10.26634/jfet.13.1.13760 Design, E-CAP, UFG, Die, Plunger The purpose of present work is to investigate the importance of 'Equal Channel Angular Pressing (E-CAP)' technique under severe plastic deformation to provide better mechanical properties and microstructure of aluminum alloy 6xxx series. The conditions for better die and plunger assembly design were experimentally found. High speed of plunger has produced bending in it, therefore, failure in E-CAP can be reduced by keeping the speed of plunger less than or equal to 1 mm/min. Route C is found most appropriate for producing large strain between passes, which can be justified by different optical microscopy images.
