Mechanical And Microstructural Analysis Of Equal Channel Angular Pressing Of Almg3 Alloy With Additional 30o Twist Angle

ABSTRACT Equal channel angular pressing (ECAP) has over the years been used as a severe plastic deformation method to refine the grains and improve the strength of various metals. Even though this has been largely successful, research over the years has tried to increase the amount of strain induced in the materials used during this process so as to further increase the strength. In this research, an additional 30o twist angle was incorporated into the outlet channel of one of the ECAP dies used to refine the AlMg3 grains. After hardness measurements were taken, this additional twist angle w…
