Abstract

In order to demonstrate that the high temperature deformation of f.c.c. and b.c.c. pure metals is controlled not by a glide process but by a recovery process, a thorough examination of distinctions between the two controlling mechanisms in issue is made, in particular in view of the effect of an experimental error involved in the strain rate change test. It is shown theoretically that the effect of the error behaves in a different manner corresponding to the two mechanisms and, in turn, the different behaviour provides an improved analysis to determine the high temperature deformation mechanism. It is presented that the result obtained by the application of the analysis to the high temperature deformation of pure Al and the other deformation characteristics of f.c.c. and b.c.c. pure metals reported so far are well explained by the recovery controlled process, in agreement with the authors' previous conclusion.
