Superplasticity in commercial Al 7475

Abstract:

Commercially produced sheets of superplastic grade Al 7475 with various thicknesses have been characterised in terms of their microstructure and mechanical properties. Gold grids deposited on polished surfaces of tensile specimens were used to measure the surface strains on mesoscopic and microscopic length scales, and fracture surfaces were examined using SEM. The results show that mechanically the alloy behaves like other superplastic materials, with a maximum strain rate sensitivity, m, of...
