Abstract

A cyclic tensile test was carried out using a plate specimen of commercial pure titanium on the stage of digital holographic microscope. The microscopic deformation of grains was observed and their height distribution was measured on the specimen surface. Each grain showed different height change from small elastic loading due to microscopic inhomogeneity, and the height change increased with the tensile load. It was found that the height change under elastic condition was correlated with that under plastic condition.
