... Induced Stress Cracking (HISC) has been demonstrated by constant load testing of specimens polarized to -1050 mV SCE . For the cold worked material Slow Strain Rate Testing (SSRT) at Test Level VI in NACE MR0175 / ISO 15156, a condition within Type 4d is discussed. With its high mechanical strength...

... hardness of 266 HV and 29.2 vol% retained austenite.16 Zappa et al. also showed that a double PWHT (650 °C and 600 °C) after austenitizing all weld metal specimens resulted in the lowest hardness and the greatest elongation in tensile specimens.17 For HAZ studies, Ramirez studied the PWHT response...

... in the vertical orientation to the printing plate using a powder bed machine equipped with twin 400 W lasers and subsequently heat treated. The specimens for SCC testing were printed as either round cylindrical bars, approximately 90 mm long with a 15 mm outer diameter, or as near-net-shape sub-size specimens...

... material values. For investigations under compressed conditions, the compression set was determined for specimens of ACM, FKM and HNBR after exposure in heating oil B0 and B20 for 3,7,14, 28, 56 and 90 days at 40 °C according to ISO 815-1. It was found that the resistance in B20 at 40 °C was given for all...

Leval Saúde, Rio de Janeiro, CEP 20081-312/RJ Aulnoye-Aymeries, F-59620 Brazil France ABSTRACT The DCB method is a crack arrest test, i.e., the specimen is self-loaded with a wedge and the constant displacement configuration makes the SIF decrease as the crack grows. Thus, KISSC provided from the DCB...

Limits for temperatures for those heat treatments were fixed considering the effect of Ni on the lower critical...

...°C, the S34700 stainless steel foil underwent breakaway oxidation after about 720 h. The N08120, N06002, N06625 and N06230 specimens presented similar mass change (less than 0.5 mg.cm -2 after 8,640 h) and comparable oxidation attack parameter (defined by the authors as the product of original foil...

... ABSTRACT The corrosion behavior of austenitic stainless steels (UNS S30400/S30403, S30800) with machined, electropolished, or temper filmed surfaces was tested in deaerated, pH adjusted water at 500 °F (260 °C), 550 °F (288 °C) and 620 °F (327 °C) for up to 10,000 hours. Test specimens were...

Crevice materials made up of 304 SS and Polyether ether ketone (PEEK) forming two kinds of crevices including 304 SS-to-PEEK and 304 SS-to-304 SS were tested, and results indicate that 304 SS specimen is strongly susceptible to crevice...

The FEA study demonstrates that a single edge notched tensile (SENT) specimen has a similar hydrogen concentration and evolution process, as well as the crack tip stress state, as an actual pipe with a surface flaw and thus it may be a relevant approach to measure pipe material sulfide stress...
