Book excerpt: Planar size effects on the fatigue crack growth rate of AISI Type 304 stainless steel characterized by linear-elastic fracture mechanics were experimentally investigated. Constant-load amplitude tests were conducted on precracked compact specimens ranging in width from 2.54 to 40.64 cm (1 to 16 in.). The da/dN versus ?K data are compared on the basis of several size criteria which are intended to limit plasticity and thus enable linear-elastic analysis of the data. Also, the cyclic J-integral method of testing and analysis was employed in the fatigue tests of several specimens undergoing gross plasticity. The cyclic J crack growth rate data agree well with that from the linear-elastic tests. It is argued that an appropriate size criterion for linear-elastic tests must limit the size of the monotonic plastic zone and thus be based on Kmax, the maximum stress intensity. While the size criteria considered vary widely in the amount of plasticity they allow, they provide comparable correlations of crack growth rate. Thus the use of the most liberal criterion is justified.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of specimen size upon the fatigue-crack growth behavior of annealed AISI Type 304 stainless steel was studied at two stress ratios at an elevated temperature. The resulting data were examined in the light of the present ASTM size criterion (based upon monotonic yield stength) as well as a proposed criterion based upon the material flow strength. The flow stress criterion is considerably less restrictive than the present ASTM Criterion, and the results of this study indicate that the flow stress criterion is entirely appropriate for strain-hardening materials such as the austenitic stainless steels.

This book was released on 1972 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fatigue-crack growth rate of Type 304 stainless steel was studied at 1000 F with cyclic frequencies ranging over approximately 4 1/2 orders of magnitude. It was found that as frequency decreased, the fatigue-crack growth rate showed a significant increase, and the behavior could be characterized by an equation of the form da/dN = A(f) [?K]n, where the exponent n represents a constant for all of the frequencies studies.

Available in PDF, EPUB and Kindle. Book excerpt: The fatigue crack-growth resistance of Type 304 stainless steel base metal and Type 308 stainless steel weld metal at 593°C (1100°F) was investigated. Specimens of both materials in the as-received (or as-welded) and thermally aged conditions were tested. The crack-growth rates were found to be exponentially related to the stress-intensity factor range, .delta. K. This relation, determined by regression analysis, was statistically appropriate and generally provided a good fit to the data. Confidence levels for new crack-growth rate observations were estimated, and comparisons of mean crack-growth rates were made. The results of the present investigation suggest the following conclusions: The fatigue crack-growth rates at 593°C (1100°F) in the Type 308 stainless steel metal are statistically lower than in the Type 304 stainless steel base metal in both the aged and as-welded (or as-received) conditions. Thermal aging at 593°C for 1000 h results in lower fatigue crack-growth rates in the base and weld metal tested at 593°C. Moreover, this difference in crack-growth rate was found to be greater than previously reported for lower-temperature tests. Load changes and hold periods at each crack-growth increment increase the scatter in results by a factor of approximately three.

This book was released on 1973 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resistance to fatigue crack growth of annealed stainless steels, Types 304, 316, 321, and 348, was determined at 77, 800, and 1100 F (25, 427, and 593 C). Crack growth rates were related to the stress intensity factor range (?K). With increase in temperature the rate of crack growth for a given (?K) increased. At room temperature the four steels had the same resistance to crack growth. However, at high temperatures crack growth became sensitive to the differences in composition and properties among the steels. At 1100 F (593 C), Type 348 steel had the greatest resistance to crack growth and Type 316 the lowest resistance. As a result, fatigue life was 3.4 times longer for Type 348 steel over Type 316 steel at this temperature. The characteristics of high-temperature fatigue crack growth were examined.
