Particle distribution of nanocrystalline copper produced by exploding wire method.

This paper presents the experimental study of electrical explosion of wire method. The sample was prepared by exploding copper wire of 0.26mm diameter in the nitrogen environment. In each time of explosion overheating factor was varied. Prepared samples were characterized by X-ray diffraction and transmission electron microscope. The result reveals the presence of copper nanoparticles and decrease of the percentage of higher size particles with increase of overheating factor. [ABSTRACT FROM AUTHOR]
