Assessment of Creep Rupture Properties of Friction Welded

The T92 martensitic and Super304H austenitic dissimilar steels welded joints were always encountered in the super critical boilers. The isothermal method was used to assess the creep rupture strength of weld joints. With the higher loading stress, the transcrystalline fracture was the rupture mode of creep specimens, and results in forming dimples. Assessment of creep rupture properties for dissimilar Jan 10, 2011 · As two new grade ferritic steel and austenitic stainless steel, T92 (9Cr0.5Mo2WVNb) and HR3C (TP310HCbN), exhibit superior heat strength at elevated temperatures and are increasingly applied in ultrasupercritical (USC) plants around the world, a complete assessment of the properties for T92/HR3C dissimilar steels welded joints is urgently

Creep Rupture Properties of High-Temperature Bainitic

Mar 01, 2000 · The heat-affected zone (HAZ) of alloy steels is usually the region of a weldment exhibiting poor mechanical properties. The arc welding of an ASTM A470, Class 8-rotor steel in this study identified the intercritical heat affected zone (ICHAZ) as the weakest region in terms of creep rupture life. Creep behavior of 316 austenitic stainless steel under and nitrogen on the creep properties of type 316 stainless steel at 873 K. Their results indicated that type 316 LN SS at 873 K in the stress range 215-335 MPa, has a lower steady state creep rate compared to type 316 SS, higher creep rupture strength and higher rupture ductility. The improvement in creep properties

the evaluation of creep behavior in this steel and in-service materials. The purpose of this work is to validate the use of SP-C testing method in the evaluation of creep properties for SUS 316 HTB austenitic stainless steel, which has been actually used as a secondary superheater tube in a fossil power plant for 100,600 h.

Creep-Resistant, Al2O3-Forming Austenitic Stainless Steels

Apr 20, 2007 · A family of inexpensive, Al2O3-forming, highcreep strength austenitic stainless steels has been developed. The alloys are based on Fe-20Ni-14Cr-2.5Al weight percent, with strengthening achieved through nanodispersions of NbC. These alloys offer the potential to substantially increase the operating temperatures of structural components and can be used under the aggressive oxidizing Embrittlement of Austenitic Stainless Steel WeldsA dramatic improvement in creep rupture properties of the austenitic stainless steel welds can be achieved by the addition of controlled residual elements (CRE).(1*-13) These are additions of small amounts of 0.5-0.6 wt-% titanium and 50-60 ppm of boron. With the titanium additions, the improvement in creep rupture properties of type 308


high-temperature strength properties should be given priority; creep or creep-rupture (sometimes called stress-rupture). If the component is small and/or the tolerances very close, such as in turbine blades, creep is regarded as the overriding factor. But if the component is large and capable of accommodating greater deformation, such as shell-and- In-beam creep rupture properties of DIN 1.4970 austenitic Nov 01, 1986 · The influence of high concentrations of helium on the creep rupture properties of an austenitic stainless steel, DIN 1.4970 SS, have been investigated at 873 K using the in-beam technique, i.e. homogeneous helium implantation during a thermal creep rupture test. It was found that this material with a special microstructure (due to thermal-mechanical treatments) is not very sensitive to helium

Influence of cerium on the creep properties of the

The creep rupture properties of the austenitic stainless steel 253MA of composition 21Cr-llNi-Si-O. 17N with and without cerium additions have been studied. Cerium reduced the number of inclusions and their elongated shape or clustered form was modified to homogeneously distributed spherical particles. Machine learning augmented predictive and generative Apr 16, 2021 · Sakthivel, T. et al.

Besides, the creep behavior of the steel is presented in the form of creep On High-Temperature Materials:A Case on Creep and

  • AbstractIntroductionExperimentalResults and DiscussionConclusionsAcknowledgmentThe creep behavior of AISI 310S stainless steel taken from SAILs Salem stainless steel plant has been investigated by constant load tensile creep test at the temperatures of 973, 1023, and 1073K and loads of 66.6, 74.8, 86.6, and 94.8MPa. It exhibits steady-state creep behavior in most test conditions.
