“…Note also that at 550 "C ductility data are strongly time dependeng but at 600°C they show less time dependency. Long-term rupture ductility for type 316 shows similar behavior with increasing time and tends to increase after long times at the lower temperature (Brinkrnan, 1985a). Figure 3 also shows that the ductility of type 316FR remains relatively high with increasing test times in comparison with types 304 and 316 stainless steel.…”

“…Figure 3 also shows that the ductility of type 316FR remains relatively high with increasing test times in comparison with types 304 and 316 stainless steel. Creep ductilities for type 316 and type 304 over the temperature range of 538 to 593°C can drop to values below 10'% (Brinkrnan, 1985a). In the case of type 304, ductility values measured by reduction of area can drop continuously to values considerably below 10% as test times approach 100,000 h. High long-term creep ductility is important in that it impmves resistance to creep-fatigue failure (Brinkman, 1985a).…”

Type 316FR stainless steel is a candidate material for the Japanese demonstration fast breeder reactor plant to be built in Japan early in the next century. Like type 316L(N), it is a low-carbon grade of stainless steel with a more closely specified nitrogen content and chemistry optimized to enhance elevated-temperature performance. Early in 1994, under sponsorship of The Japan Atomic Power Company, work was initiated at Oak Ridge National Laboratory (ORNL) aimed at obtaining an elevated-temperature mechanical-properties database on a single heat of this material. The product form was 50-mm plate manufactured by the Nippon Steel Corporation. Data include results from long-term creep-rupture tests conducted at temperatures of 500 to 600°C with test times up to nearly 40.000 h, continuous-cycle strain-controlled fatigue test results over the same temperature range, limited creep-fatigue data at 550 and 600°C, and tensile test properties from room temperature to 650°C. The ORNL data were compared with data obtained from several different heats and product forms of this material obtained at Japanese laboratories. The data were also compared with results from predictive equations developed for this material and with data available for types 316 and 316L(N) stainless steel.

A titanium alloy, IMI 829 and a superalloy MAR Μ 002 tested under high temperature low cycle fatigue (HTLCF) at the University of Bristol, U.K., were examined for metallographic and fractographic features and the results are shown in this paper. From these observations a new five stage damage development model was developed for the HTLCF of IMI 829 and MAR Μ 002. It was shown that under creep-fatigue test conditions oxidation occurs which contributes to the development of cracks and their propagation for which, in general, no quantitative tool exists that can be accounted in HTLCF life prediction.

“…High temperature fatigue involves many complex processes such as creep effects 11-31, surface oxidation attack [4-111, local precipitation along grain boundaries [12][13][14] etc. Although there are many difficulties in understanding high temperature effects by means of experimental analyses, useful results have been published on the nature of high temperature fatigue [I [15][16][17][18].…”

Surface and In‐depth Crack Propagation in High Temperature Low‐cycle Fatigue of Sus 316 Stainless Steel

The low-cycle fatigue crack propagation behaviour of surface cracks in SUS316 stainless steel at 700"C, in both the surface direction and the in-depth direction, has been studied with special emphasis on the role of oxidation. The coalescence behaviour of surface cracks is essential for the process of crack propagation in high temperature low cycle fatigue, irrespective of the existence of oxidation effects. For sub-surface cracks the process of crack propagation is divided into two stages characterized by differences in fracture mode. In both stages, the in-depth crack propagation rate in air is higher than that in vacuum. This difference in crack propagation rate is the main reason for the decrease of fatigue life in air compared with that in vacuum. The crack propagation behaviour in the in-depth direction can be estimated from the conversion of the surface crack length into the subsurface depth by the use of an aspect ratio.
