Abstract

Electropulsing induced microstructual changes and phase transformations in nanofilms of Zn-Al based alloys were studied by X-ray diffraction and scanning electron microscopy techniques. It was found that electropulsing affected considerably crystal orientation of nanophases. Also, electropulsing tremendously accelerated nanophase decomposition (such as formation of Z-zones and transitional phases). After electropulsing, the electric resistances of nanofilms of ZA22 and ZA27 reduced for 16.6% and 18.2%, respectively. Effect of electropulsing induced preferred crystal orientation changes on nanophase decomposition and electric conductivity of the Zn-Al based alloys is discussed.
