Crack Tip Plasticity Associated with Corrosion Assisted Fatigue.
Abstract
This is the seventh and final Annual Report on this research project entitled 'Crack Tip Plasticity Associated with Corrosion Assisted Fatigue.' The objective of this program has been to examine the effect of environment on the deformation response of the material near the crack tip-the plastic zone-and from that response, determine the effect of environment on fatigue crack growth. The results described in this report were obtained using essentially two techniques: the relatively new technique stereoimaging, coupled with the use of a cyclic loading stage for the scanning electron microscope, and the now standard technique of electron fractography, using the SEM. The effect of environment on aluminum and titanium alloys was determined by analyzing cracks grown in both moist and very dry environments.
