摘要：

The notch sensitivity of 95% cold-rolled Ni3Al foils was examined using double U-notched tensile specimens. The foils were found to be essentially insensitive to the presence of the notch. Plastic deformation occurred locally at the notch root to relieve the stress concentration, resulting in the notch insensitivity. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd.
