متن کاملHydrogen Embrittlement of Duplex Steel Tested Using Slow Strain Rate Test
P. Vaňová, J. Sojka. VŠB Technical u niversity of O strava, FMME, Ostrava, Czech Republic This paper is dealing with hydrogen embrittlement of austenitic-ferritic 2205 duplex steel using the slow strain rate test (SSRT). The original material was subjec ted to heat treatment under 700 °C during 5 hours and f ollowing aircooling with the aim of pr ovoking sigma phase pr ecipitation and embrittle...
متن کاملHydrogen Embrittlement of High Strength Steel Electroplated with Zinc-cobalt Alloys
Slow strain rate tests were performed on quenched and tempered AISI 4340 steel to measure the extent of hydrogen embrittlement caused by electroplating with zinc-cobalt alloys. The effects of bath composition and pH were studied and compared with results for electrodeposited cadmium and zinc-10%nickel. It was found that Zinc-1%cobalt alloy coatings caused serious hydrogen embrittlement (EI 0.63...
متن کاملWarm Pre-Strain: Strengthening the Metastable 304L Austenitic Stainless Steel without Compromising Its Hydrogen Embrittlement Resistance
Plastic pre-strains were applied to the metastable 304L austenitic stainless steel at both room temperature (20 °C) and higher temperatures (i.e., 50, 80 and 100 °C), and then the hydrogen embrittlement (HE) susceptibility of the steel was evaluated by cathodically hydrogen-charging and tensile testing. The 20 °C pre-strain greatly strengthened the steel, but simultaneously significantly increa...
متن کاملPrevention of Hydrogen Embrittlement in Steels
The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years. It is diffusible hydrogen that is harmful to the toughness of iron. It follows, therefore, that the harmful influence of diffusible hydrogen can be mitigated by preventing its entry into steel or by rendering it immobile once it penetrates the material. This review deals with the meth...
