Publication Abstract: 

The purpose of this study is to characterize the effects of heat damage on the electrical
conductivity and static mechanical properties of aluminum alloys. The data resulting from the
experiments of thermal exposure of several aluminum alloys are used to model the relations that
describe the dependence of the electrical conductivity and hardness on the two main variables of
these experiments: the temperature and the time of exposure. The dependence of yield strength and
ultimate tensile strength on hardness values is characterized. For each case, different materials
(alloys) exhibit similar general trends although there are different coefficients for each material to
satisfy the general relation.
