Abstract

An Ashby-type deformation mechanism map may be considerably simplified by plotting in the form of normalized stress versus the reciprocal of the homologous temperature. In this form, the boundaries separating the various fields appear as straight lines and the constant strain rate contours may be approximated as straight lines. Representative maps are presented for conditions of high temperature creep, and a simple procedure is outlined for constructing several maps for the same material at different grain sizes.
