The electrical resistivity of GP zones Temperature dependence

Abstract

The influence of the measuring temperature on the resistivity of GP zone-forming alloys is investigated theoretically in the light of recent measurements. The current theory explains the observations satisfactorily: for spherical clusters the measuring temperature has little influence on the resistivity, while for platelets, an increase in measuring temperature leads to a substantially higher peak resistivity occurring at a later ageing time.

It remains slightly mysterious that the measuring temperature has absolutely no detectable influence in the case of Al-Zn.
