摘      要：Constrained groove pressing(CGP)is a severe plastic deformation(SPD)technique used as a strengthening method for sheet *** the current work,an optimal/cost-saving design for CGP dies was attained using the stress analysis tool in SolidWorks Simulation Xpress *** study examined low-cost and widely industrially applied aluminium materials,i.e.,pure 1050 Al and 5052 Al *** material was subjected to three passes of the CGP process using a 150 tons capacity *** both materials,inter-pass annealing treatment was undertaken before the third *** effect of the number of CGP passes on the microstructure and tensile properties was studied after each *** CGPed pure 1050 Al with respect to the as-received material,the ultimate tensile strength(UTS),yield strength(YS)and YS/UTS ratio increased with an increasing number of CGP passes until the second pass,while elongation decreased with the number of *** CGPed 5052 Al alloy,the UTS and YS increased after the first pass and then decreased after the second *** in the elongation and YS/UTS ratio of 5052 Al alloy after the CGP process were *** inter-pass annealing and applying the third CGP pass,the strength of pure 1050 Al decreased,and that of 5052 Al alloy increased,which was attributed to the influence of composition on their *** strength-ductility balance decreased with an increasing number of CGP passes in both materials.
