Abstract:

By a test involving a combination of static and dynamic loading, the carboxylic acids are shown to be embrittling to high-strength steel to a degree proportionate to the carbon chain length. It is shown that nonpolar liquids are in general not embrittling but that the magnitude of the dipole moment is not a measure of embrittling propensity. Evidence indicates that under appropriate conditions, a -Cl group is potentially as embrittling as an -OH or a -O- group. See also AD-427 068.
