Abstract
Acoustic emission behavior during tensile deformation of single crysta ls and unidirectionally solidified specimens of Ni3Al intermetallic co mpound was studied. Mobile dislocation behavior in single crystals was investigated by measuring acoustic emission rms voltage. Using unidir ectionally solidified specimens, effects of grain boundaries parallel to tensile axis on the acoustic emission behavior during tensile defor mation of Ni3Al was examined. It was made clear that blocking dislocat ions at grain boundaries and microcracking along grain boundaries are acoustic emission sources. Published by Elsevier Science Limited. All rights reserved.
