Hydrogen effects in high-purity stainless steels

Description: Internal and environmental hydrogen damage to three pure stainless steels (19% Cr and 10, 14 or 19% Ni) were evaluated by tensile tests. Concentrations of C, Mn, Si and P were less than in commercial alloys. Susceptibility of the pure alloys to hydrogen damage was comparable to that of commercial austenitic stainless steels. 3 figures, 4 tables.

The potential of modified type 310 stainless steel for advanced fossil energy applications

Description: An evaluation was undertaken to determine the potential of modified type 310 stainless steel for fossil energy applications. First, alloy performance criteria for components in several emerging technologies were identified. Then, a brief review of existing alloy technology was undertaken relative to performance criteria. Key issues were the tendency for type 310 stainless steel to embrittle due to the formation of intermetallic phases, the poor resistance of type 310 stainless steel to highly s… more

Determination of creep compliance and creep-swelling coupling coefficients for neutron-irradiated titanium-modified stainless steel at @400 degree C

Description: Irradiation creep data from FFTF-MOTA at {approximately}400{degrees}C were analyzed for nine 20% cold-worked titanium-modified type 316 stainless steels, each of which exhibits a different duration for the transient regime of swelling. One of these steels was the fusion prime candidate alloy designated PCA. The others were various developmental breeder reactor heats. The analysis was based on the assumption that the B{sub 0} + DS creep model applies to these steels at this temperature. This ass… more

The effects of tritium and decay helium on the fracture toughness properties of stainless steels

Description: J-integral fracture mechanics techniques and scanning electron microscopy observations were used to investigate the effects of tritium and its decay product, helium-3, on Types 304L, 316L, 21-6-9, A286, and JBK-75 (Modified A286) stainless steels. Tritium-exposed samples of each steel had lower fracture toughness values and less resistance to stable crack growth than control samples. Type 316L stainless steel was more resistant to the embrittling effects of tritium and decay helium than the oth… more

Corrosion in lithium-stainless steel thermal-convection systems

Description: The corrosion of types 304L and 316 austenitic stainless steel by flowing lithium was studied in thermal-convection loops operated at 500 to 650/sup 0/C. Both weight and compositional changes were measured on specimens distributed throughout each loop and were combined with metallographic examinations to evaluate the corrosion processes. The corrosion rate and mass transfer characteristics did not significantly differ between the two austenitic stainless steels. Addition of 500 or 1700 wt ppM N… more

Experimental study of plastic responses of pipe elbows

Description: Load-deflection responses were determined experimentally for sixteen 152.4-mm (6-in.) (nominal) commercial carbon steel pipe elbows and four 152.4-mm (6-in.) stainless steel elbows. Each specimen was loaded with an external force of sufficient magnitude to produce predominantly plastic response. The influences of bend radius and wall thickness were studied, as well as the effect of internal prssure on load-deflection behavior. Comparisons of results from stainless steel and from carbon steel el… more

Effects of commercial cladding on the fracture behavior of pressure vessel steel plates

Description: The objective of this program is to determine the effect, if any, of stainless steel cladding upon the propagation of small surface cracks subjected to stress states similar to those produced by thermal shock conditions. Preliminary results from testing at temperatures 10/sup 0/ and 60/sup 0/C below NDT have shown that (1) a tough surface layer (cladding and/or HAZ) has arrested running flaws under conditions where unclad plates have ruptured, and (2) the residual load-bearing capacity of clad … more

Interim fatigue design curves for carbon, low-alloy, and austenitic stainless steels in LWR environments

Description: Both temperature and oxygen affect fatigue life; at the very low dissolved-oxygen levels in PWRs and BWRs with hydrogen water chemistry, environmental effects on fatigue life are modest at all temperatures (T) and strain rates. Between 0.1 and 0.2 ppM, the effect of dissolved-oxygen increases rapidly. In oxygenated environments, fatigue life depends strongly on strain rate and T. A fracture mechanics model is developed for predicting fatigue lives, and interim environmentally assisted cracking … more

Inertia and friction welding of type 1100 aluminum to type 316 stainless steel

Description: The inertia and friction-welding processes were evaluated for joining Type 1100-H14 aluminum to Type 316 VIM VAR stainless steel. While both processes consistently produce joints whose strength exceed the aluminum base metal, 100 percent bonding has not been reliably achieved. This deficiency points out the need for the development of nondestructive testing techniques for this type of joint. Additionally, solid state volume diffusion did not appear to be a satisfactory explanation for the inert… more

Corrosion Tests in Molten Lead-Lead Chloride

Description: Corrosion tests were run on some commercial grade metals, an alloy steel, stainless steels, chromium-- nickel-iron alloys, nickel base alloys, cobalt base alloys, and a chromium-- nickel-- cobalt-- iron ailoy in the system: leadlead chloride-lead chloride vapor at 528 deg C under an argon atmosphere. The following metals and alloys showed a corrosion rate of nine mils per month or less and did not suffer intergranular or other localized attack: tantalum, Incoloy 804, Hastelloy F, Carpenter-20 (… more

Influence of cold work level on the irradiation creep and creep rupture of titanium-modified austenitic stainless steels

Description: A titanium-modified austenitic type stainless steel was tested at three cold work levels to determine its creep and creep rupture properties under both thermal aging and neutron irradiation conditions. Both the thermal and irradiation creep behavior exhibit a complex non-monotonic relationship with cold work level that reflects the competition between a number of stress-sensitive and temperature-dependent microstructural processes. Increasing the degree of cold work to 30% form the conventional… more

Fatigue crack propagation in Types 304 and 308 stainless steel at elevated temperatures

Description: The fatigue crack-growth resistance of Type 304 stainless steel base metal and Type 308 stainless steel weld metal at 593/sup 0/C (1100/sup 0/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 th… more

Thermal Conductivity and Thermal Expansion of Stainless Steels d9 and ht9

Description: Renewed interest in the use of metallic fuels in liquid-metal fast breeder reactors has prompted study of the thermodynamic and transport properties of its materials. Two stainless steels are of particular interest because of their good performance under irradiation. These are D9, an austenitic steel, and HT9, a ferritic steel. Thermal conductivity and thermal expansion data for these alloys are of particular interest in assessing in-reactor behavior. Because literature data were inadequate, me… more

Role of ferrite and phosphorus plus sulphur in the crack sensitivity of autogenously welded type 309 stainless steel

Description: A study on autogenous welding of Type 309 thin stainless steel sheet was made after experiencing cracking difficulties on several commercial heats. A relationship exists between the sum of the phosphorus plus sulfur, the ferrite control of the weld metal, and the crack sensitivity of autogenously made welds. A new simple weld test for thin-gage sheet is utilized for studying the susceptibility to cracking. A chemistry modification is suggested to alleviate possible weld cracking when autogenous… more
