X-Ray Analysis of Accrued Damage in Stress Corrosion and Corrosion Fatigue.

Abstract

The defect structure induced in 304 austenitic stainless steel by stress corrosion and in Al 2024 by corrosion fatigue was studied by X-ray rocking curve measurements of the grains and by X-ray Fourier analysis of the line profiles. The surface layer and bulk of the specimens were investigated, and a critical line width parameter corresponding to a critical excess dislocation density was determined that controlled the integrity of the microstructure. Improvements in the speed and efficiency of data collection were made by instrument automation and application of position-sensitive detectors. (Author)
