Download or read book Low Cycle Fatigue Behavior of Types 304 and 316 Stainless Steel at LMFBR Operating Temperature written by CF. Cheng and published by . This book was released on 1973 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fully reversed, axial strain-controlled low-cycle fatigue tests with and without tension holdtime have been conducted in air in the temperature range of 806 to 1202 F and at a strain rate of 4 x 10-31 on Types 304 and 316 stainless steel after various initial heat treatments. The test results have been supplemented by metallographic and scanning electron microscopy investigations. Prior heat treatment has a greater effect on specimens tested at 1050 F than on those tested at 1202 F and a greater effect on Type 304 than on Type 316. The introduction of tension holdtimes decreases the cyclic life of both materials and causes the mode of failure to change from transgranular to intergranular. Much of the above fatigue behavior can be qualitatively understood on the basis of the supplemental metallographic results.

Available in PDF, EPUB and Kindle. Book excerpt: Fatigue tests in sodium were conducted to investigate the influence of a high-temperature sodium environment on the low-cycle fatigue behavior of Types 304 and 316 stainless steel. The effects of testing in a sodium environment as well as long-term sodium exposure were investigated. The fatigue tests were conducted at 600 and 700°C in sodium of controlled purity, viz., approximately 1 ppM oxygen and 0.4 ppM carbon, at a strain rate of 4 x 10−3s−1. The fatigue life of annealed Type 316 stainless steel is substantially greater in sodium than when tested in air; however, the fatigue life of annealed Type 304 stainless steel is altered much less when tested in sodium. A 1512-h preexposure to sodium had no significant effect on the fatigue life of Type 316 stainless steel tested in sodium. However, a similar exposure substantially increased the fatigue life of Type 304 stainless steel in sodium. 10 fig. (auth).

Download or read book Effects of Environment on the Low cycle Fatigue Behavior of Type 304 Stainless Steel written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The low-cycle fatigue behavior of Type 304 stainless steel has been investigated at 593/sup 0/C in a dynamic vacuum of better than 1.3 x 10/sup -6/ Pa (10/sup -8/ torr). The results concerning the effects of strain range, strain rate and tensile hold time on fatigue life are presented and compared with results of similar tests performed in air and sodium environments. Under continuous symmetrical cycling, fatigue life is significantly longer in vacuum than in air; in the low strain range regime, the effect of sodium on fatigue life appears to be similar to that of vacuum. Strain rate (or frequency) strongly influences fatigue life in both air and vacuum. In compressive hold-time tests, the effect of environment on life is similar to that in a continuous-cycling test. However, tensile hold times are nearly as damaging in vacuum as in air. Thus, at least for austenitic stainless steels, the influence of the environment of fatigue life appears to depend on the loading waveshape.

This book was released on 2013-03-09 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the effort devoted to assuring both the safety and reliability of commercial nuclear fission power reactors has markedly increased. The incentives for performing this work are large since the resulting im provement in plant productivity translates into lower fuel costs and, more importantly, reduced reliance on imported oil. Reliability and availability of nuclear power plants, whether fission or fusion, demand that more attention be focused on the behavior of materials. Recent experiences with fission power indicate that the basic properties of materials, which categorize their reliable behavior under specified conditions, need reinforcement to assure trouble-free operation for the expected service life. The pursuit of additional information con tinues to demand a better understanding of some of the observed anom alous behavior, and of the margin of resistance of materials to unpre dictable service conditions. It is also apparent that, next to plasma heating and confinement, materials selection represents the most serious chal lenge to the introduction of fusion power. The recognition of the importance of materials performance to nu clear plant performance has sustained a multimillion dollar worldwide research and development effort that has yielded significant results, both in quantification of the performance limits of materials in current use and the development and qualification of new materials. Most of this infor mation appears in the open literature in the form of research reports, journal articles, and conference proceedings.
