Abstract

The aluminum-lithium alloy 2090-T8E41 undergoes delamination along certain high-angle boundaries parallel to the rolling plane when subjected to torsional loading. Weak boundaries were located by comparison of fracture surface replicas and thin foils in the electron microscope. Grain boundary orientation was determined from Kikuchi patterns obtained by convergent beam electron diffraction.
