    Abstract

    A new type of specimen for determining stress corrosion threshold stress is described. The specimen has a tapered gage length that provides longitudinal stress distribution with a maximum to minimum stress ratio of 1.85. After a constant load stress corrosion test, the surface of the specimen is inspected and the gage length is longitudinally sectioned. In long-time tests the minimum stress at maximum diameter at which cracking is found approaches the threshold value. Applicability of the specimen has been confirmed by tests of several materials in different environments. The specimen can also be used for the testing of stress-induced pitting.
