Note on correction factor for estimating the diameter of embedded cylindrical fibres from metallographic sections

This article recalculates the correction factor for estimating the diameter of aligned cylindrical fibres from random metallographic sections as put forward in the paper of Lewis and Withers [Acta Metall. Mater. 43 (1995) 3685]. Their assertion may contain typographic and arithmetic errors (leading to an error of a factor of 2). The diameter must be estimated from longitudinal metallographic sections where the fibre diameters are partially embedded and therefore cannot be measured directly. In view of the high level of citations of the original paper, it is important to address this problem accurately and completely to ensure the successful application of their suggested method by others. The purpose of this short note is to correct their results. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
