Abstract

In this work optical microscopy in situ tensile testing has been carried out to study the localisation of surface strain in fully lamellar titanium alloys. The localised strain was measured by analysing the recorded optical micrographs using image correlation, and the orientation of the a lamellae colony was determined by using Electron Back Scatter Diffraction (EBSD). The results show a localisation of strain, which seems to depend on the crystallographic orientation of the alpha lamellae colony in the lamellar microstructure. No significant strain was observed in the former beta grain boundary region. ; Times Cited: 0 International Conference on Advances in Experimental Mechanics SEP 06-08, 2004 York, ENGLAND British Soc Strain Measurement
