MONTEMAYOR-ALDRETE, J.A.; MUNOZ-ANDRADE, J.D.  and  MENDOZA-ALLENDE, A.. On the correlation between Fe concentration and the activation energy for superplastic deformation in Zn-22 pct Al. Rev. mex. fis. [online]. 2002, vol.48, n.3, pp.210-214. ISSN 0035-001X.

For the first time, an expression for the apparent activation energy for superplastic deformation in Zn-22 pct Al doped with Fe impurities, which exhibits in an explicit fashion the Fe-concentration has been obtained. Such expression allows to describe all the experimental data previously reported. The range of Fe-concentration for which the Mohamed's model remains valid is established.

Keywords : Activation energy; superplasticity; threshold stress; segregation.
