Tensile Properties of 1060 Al Alloy Subjected to Constrained Groove Pressing
Three groups of commercial 1060 Al alloy sheets were subjected to constrained groove pressing (CGP) at room temperature using parallel CGP, 180° cross CGP and 90° cross CGP, respectively. Tensile properties and fracture modes of as-annealed and CGPed samples were investigated. The ultimate tensile strength (UTS) of 1060 Al increases significantly after CGP, while the elongation decreases. But they are strongly dependence on the number of CGP passes and the pressing modes. The UTS and elongation of the samples processed by 90° cross CGP are best, consequently, the static toughness of the 90° cross CGPed samples is enhanced. Besides, all CGPed specimens failed in a ductile manner. With increasing the number of CGP pass, the amount of small dimples increases, and the dimples become shallow and more uniform.
