摘要：

A technique based on high-speed digital photography and image correlation for direct whole-field strain mapping of Portevin-Le Chatelier deformation bands is described. Results for a type B band show that the deformation band was formed within a few milliseconds and remained stationary as no motion of the band was detected. © 2005 Published by Elsevier Ltd. on behalf of Acta Materialia Inc.
