(PDF) Fatigue behavior of AISI 304 stainless steel under

This study presents the fatigue response of 304 stainless steel foil, cold rolled to a thickness of 3.2 µm with 87 percent cold work at orientations of 0, 45, and 90 degrees to the direction of

Corrosion fatigue behavior of 304 stainless steel notched

Mar 04, 2019 · Fatigue behavior of 304 stainless steel notched specimen was investigated in room-temperature (RT) air, 280 °C and 325 °C pressurized water at varying average strain rates. Fatigue life of the notched specimen in RT air is longer than that of the smooth specimen due to the stress gradient on the section of notch root. Effect of various atmospheres on the threshold fatigue The threshold fatigue crack growth (FCG) behavior of AISi 304 austenitic stainless steel was investigated under three different atmospheres:dry argon, hydrogen and moist air.

Fatigue Crack Propagation Rates for Notched 304 Stainless

Aug 18, 2004 · Fatigue crack propagation (FCP) rates for 304 stainless steel (304 SS) were determined in 24°C and 288°C air and 288°C water with 2060 cc H 2 / kg H 2 O using double-edged notch (DEN) specimens. Tests performed at matched loading conditions in air and water provided a direct comparison of the relative crack growth rates over a wide range of test conditions. Fatigue crack propagation in Types 304 and 308 stainless The fatigue crack-growth behavior of Type 304 stainless-steel base metal and Type 308 stainless-steel weld metal at elevated temperature was investigated using axially loaded single-edge-notch specimens. The crack-growth rates were determined and are presented as a function of the stress-intensity factor range.

Fatigue, tensile, and relaxation behavior of stainless

OSTI.GOV Technical Report:Fatigue, tensile, and relaxation behavior of stainless steels Title:Fatigue, tensile, and relaxation behavior of stainless steels Full Record Fatigue-crack propagation behavior of type 304 stainless Jan 01, 1975 · The fatigue crack growth of Type 304 stainless steel in a liquid sodium environment at 800 and 1000°F was characterized using a linear-elastic fracture mechanics approach. Tests were conducted in low (< 2.0 ppm) and high (20-40 ppm) oxygen sodium and the results were compared to those of tests conducted in vacua and in air.

Fretting Fatigue Behavior of 304 Austenitic Stainless Feb 07, 2017 · Effect of mean stress on fretting fatigue behavior of 304 austenitic stainless steel has been investigated by conducting fretting fatigue tests at a constant contact pressure of 100 MPa under three different mean stresses i.e., 0, 350 and 450 MPa. For comparisons, plain fatigue tests were also carried out. The influence of tensile overload on fretting fatigue life was also investigated.

The Influence of Hydrogen on Corrosion Fatigue Crack

Corrosion fatigue crack growth rates (FCGRs) in Type 304/304L stainless steel containing different levels of sulfur are observed to vary significantly during testing at high stress ratios in elevated temperature (288 338°C) deaerated pressurized water (DPW). The effect of overload on the fatigue crack growth Jul 07, 2008 · Abstract. Fatigue crack growth (FCG) behaviour and its characteristics following tensile overloads were investigated for AISI 304 stainless steel in three different atmospheres; namely dry argon, moist air and hydrogen. The FCG tests were performed by MTS 810 servohydraulic machine.
