Effect of cold plastic deformation on electrical conductivity of various materials

This study is focused on the investigation of the effect of cold plastic deformation on the electrical conductivity properties of different materials. The plastic deformation that occurs at the upsetting of the specimen and the varying of the conductivity properties were the main subject of this study. Aluminium, copper and brass were used as the test materials in the experiments. Measurement results of the upset (deformed) specimens were obtained with a conductivity meter instrument. Result which was obtained from the experiments was presented graphically. Finally, it is concluded that in general electrical conductivity decreases slightly due to plastic deformation of the deformed materials. (C) 2008 Elsevier Ltd. All rights reserved.
