摘要：

In this paper is presented the results of an experimental study aimed at understanding the tensile deformation and fracture behavior of aluminum alloy 2219. Uniaxial tensile tests results reveal the alloy to have acceptable strength and ductility (elongation-to-failure) for both the anodized and non-anodized conditions. The ductility, quantified in terms of reduction in area, of the anodized sheet is marginally superior to the ductility of the non-anodized sheet. No drastic change in tensile fracture mode was evident as a function of anodized condition of the sheet. On a microscopic scale, tensile fracture surfaces of the alloy revealed features reminiscent of locally ductile and brittle failure mechanisms. The fracture behavior of the alloy is discussed in light of intrinsic microstructural features; deformation characteristics of the alloy, local stress state and grain boundary failure. 0 2008 Elsevier B.V.
