Influence of the Texture on Mechanical Properties of the Al-Li Alloy 1441

Accepted28 Sep 1997

Abstract

Results of texture investigations in sheet and plate of the Al–Li alloy 1441 are presented. The peculiarities of fracture surface morphology formation during fatigue crack propagation tests in dependence on texture inhomogeneity are considered. The deviation of the fatigue crack from the principal direction in center-notched specimens could be related to occurrence of a {110} 112 texture. The formation of crystallographic faceted fracture surfaces results from cracks extending by slip along equally shear stressed {111} 110 slip systems ahead of the crack tip.
