The Influence of Loading Mode on the Stress Corrosion Susceptibility of Various Alloy/Environment Systems.
Abstract
The influence of loading mode on stress-corrosion susceptibility has been examined for the following systems: Ti- 8Al 1Mo 1V alloy/aqueous chlorides; alpha - brass/ammoniacal environments, 7075-T6 Al alloy in NaCl/K2Cr2O7 solutions. With the exception of the alpha- brass/ammonia system, the stress-corrosion susceptibility of the metals was found to be much greater under tensile (mode I) loading than torsional (mode III) loading. Further, in certain instances the addition of hydrogen-recombination (cathodic) poisons, i.e., arsenic, was found to enhance susceptibility to cracking as a function of loading mode is interpreted to indicate that hydrogen damage is the dominant mechanism leading to failure. Implications of these results to mechanistic understanding are discussed.
