Characterization of Boundary Misorientations in a Superplastic Al-Alloy Hot-Deformed by ECAE

Abstract:

Microstructure and boundary populations were investigated in a superplastic Al-5.5%Mg- 2.2%Li-0.12%Zr alloy hot-deformed by equal channel angular extrusion. The microstructure was found to be inhomogeneous and revealed deformation structures being subdivided by both low- and high-angle boundaries.
