About the Journal :
Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of nanotechnology with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics, materials science and medicine. ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
Positron Annihilation Lifetime (PAL) and X-ray are common nondestructive techniques used heavily in materials science to detect deformation and thermal effects in metals and alloys. In this work, the investigated wrought 1070 Al-alloy samples were plastically deformed at room temperature using a hydraulic press. X-ray diffraction patterns of the bulk and the deformed 1070 Al-alloy, at different degrees of deformation, have been studied and analyzed using MAUD program. The lattice parameter, the grain size and the intensity ratio of the maximum diffraction lines in addition to micro-strain as a function of the degree of deformation have been determined. The 20 % deformed sample was annealed and the behavior of the positron annihilation mean lifetime of the sample was studied as a function of the annealing temperature.
