Results of High R-Ratio Fatigue Crack Growth Tests on 304 Stainless Steel in Low Oxygen Water

PDF Version Also Available for Download.

Description

Fatigue crack growth rate tests were performed on a 304 stainless steel compact tension (CT) specimen in water with 40-60 cc/kg H[sub]2. Data in the literature for CT tests show minor environmental effects in hydrogenated water, but higher effects in oxygenated water. However, the PWR data presented by Bernard, et al (1979) were taken at low stress ratios (R=0.05) and high stress intensity levels (delta K=16-41 MPa square root m). The purpose of these tests is to explore the crack growth rate characteristics of 304 SS in hydrogenated water at higher R values (0.7 and 0.83) and lower delta K ... continued below

The purpose of these tests is to explore the crack growth rate characteristics of 304 SS in hydrogenated water at higher R values (0.7 and 0.83) and lower delta K values (11.0 and 7.7 MPa square root m). Each set of R, delta K conditions were tested at frequencies of 0.1, 0.01 and 0.001 Hz. The results show a pronounced effect on crack growth rates when compared to available literature data on air rates.
