An evaluation program was conducted on Type 316 stainless-steel sheet material to determine the effects of residual cold-work and welding on the room-temperature and elevated-temperature mechanical properties to 1800 deg F. Short-time tensile and tensile-creep elongations tests were run to determine the stresses required to produce elongations up to 10 per cent in 2 min. The effect of welds in tension was to lower the elongation with no loss in strength. The effect of cold-work on the annealed material was to increase appreciably the strength properties, thus allowing for higher design stresses. The results of a few tests indicate that Type 316 stainless steel retains some strength properties up to 2300 deg F. A definite stress-strain relationship exists in which the 0.2 per cent yield stress is very close to the tensile stress.

Laminated Materials

The approach for graphite laminated materials strength properties prediction using contact angle measurements was proposed. The tensile strength of laminated materials made of graphite foil and stainless steel with acrylic and silicone adhesives was measured. It was shown that tensile strength depends on energy characteristics of polymer binders, which can be determined by simple and express wetting method. It was found that the highest values of tensile strength, strength of adhesion and the work adhesion to graphite and stainless steel were provided by acrylic adhesive MBM-5C. The delamination occurred when graphite and stainless steel sheets were connected with low surface energy silicone resin, γ = 23 mJ/m2,<br />what was not able to maintain sufficient adhesion level to the both types of attached surfaces: polar steel and non-polar graphite. It was demonstrated that the calculation of the work of adhesion to polar and non-polar model liquids (water and octane respectively) can be applied to optimize the choice of polymer binder and design of laminated materials. It’s quite important that the proposed technique doesn’t require to determine free surface energy for each type of sheet material which is especially difficult and complex task if laminate consists of several different layers.

Rupture Behavior

Available equipment initially developed for welding research studies was used to investigate the creep-rupture behavior of AISI type 347 stainless steel in a very-high-temperature range from 62 to 86 percent of the solidus. Stress applications from 900 to 28,000 psi gave rupture times from a fraction of a second to several hundred seconds with thousandfold variations of minimum creep rate. Results could be presented by conventional means. Data scatter on a Monkman-Grant plot was typical. Correlation and extrapolation procedures developed by Larson-Miller, Manson-Haferd, Dorn, Korchynsky, and Conrad for conventional long-time results were found to be applicable, with preference being given to the Manson-Haferd procedures.

ABSTRACTMicrostructural examination and in situ post-irradiation annealing studies were carried out on 20% cold-worked 316 stainless steel (SS) hexagonal duct material following irradiation in the reflector region of the EBR-II reactor. Stainless steel hexagonal ducts were used to house reactor subassemblies and provide a valuable source of information on irradiation behavior of reactor structural materials at lower dose-rates (on the order of 10-8 dpa/sec) than previously examined. The microstructural development of samples irradiated to doses of 1, 20 and 30 dpa is examined, while the post-irradiation annealing behavior of a sample irradiated to 20 dpa is described. Annealing studies were performed at 370 and 500°C to examine the kinetics of radiation damage recovery as a function of annealing temperature. The initial (pre-annealed) microstructures consists of a substantial density of irradiation induced chromium-rich M23C6 and M6C carbides which form both on the grain boundaries and within the grain interiors. Recovery of the cold- work is evident in the 1 dpa sample while samples irradiated to 20 and 30 dpa possess dense populations of voids and dislocation structures consisting of networks of line dislocations and faulted dislocation loops. Results indicate that post-irradiation annealing of the samples at 370°C for 1 hour has little effect on the microstructure, while further annealing at 500°C for 1 hour results in void shrinkage, the formation of small cavities, and a reduction in the dislocation loop and network density.
