Abstract
Cold-drawn pearlitic steel wires are widely used in numerous engineering fields. Combining X-ray line profile analysis and positron annihilation spectroscopy methods, up to 10(-5)-10(-4) vacancies were found in a-ferrite of a cold-drawn pearlitic steel wire with a true strain of epsilon = 3. The formation of deformation-induced vacancies in alpha-ferrite of cold-drawn pearlitic steel wire was quantitatively testified. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd.
