Abstract By using SMAs formulations based on Cu-Zn-Al, the electrical resistivity by employment of an Agilent 4294A Precision Impedance Analyzer was analysed. It results that different percentages metals which make up SMA, do have important influence upon resistivity. In particular, for one analyzed samples, it observed SME manifested as a form “electric properties” memory. The experimental dat...

In this article, commercially pure copper samples were severely deformed by equal channel angular pressing (ECAP) up to eight passes at room temperature. The effects of severe plastic deformation on the microstructure, mechanical properties, and electrical conductivity of the copper were investigated. The microstructure evolution was followed by optical microscope and field emission scanning el...
