Abstract

It is shown that even when all the specimens used in a testing programme are taken from a single industrially prepared sheet, significant scatter in the mechanical properties of a superplastic alloy may be present but will not be revealed if the data are presented as log (stress)-log (strain rate) plots. A comparison of the linear stress-strain curves of different specimens for consistency is necessary before using them for microstructural and texture studies.
