... ABSTRACT Two commonly used aluminum alloys, namely 5083 and 6061, in fabrication of Aluminum Plate Heat Exchangers (APHE) were tested under four-point bending at different volumes of mercury and stress to measure their susceptibility to liquid metal embrittlement (LME) by mercury. The test...

... ABSTRACT The technical suitability of the steel grades L80 and 42CrMo4 (UNS G41400) for the application in an underground gas production facility is investigated. Therefore, the materials are tested with respect to their susceptibility to embrittlement by hydrogen gas, up to a maximum H 2...

... of the failure analysis cases from oil and gas production was related to failure of fasteners, 65 percent of which originated through brittle fracture, including hydrogen embrittlement. 5 Although the frequency of bolt failures is relatively low (of the order of 10 -4 per year), the consequences of bolt...

The aim of this paper is to draw attention to the risk of inservice embrittlement of duplex stainless steels, highlighting the difference in susceptibility...

...)duplex stainless steels, (S)DSSs, are of particular interest in oil and gas applications, due to their combination of high strength and corrosion resistance. However, (S)DSSs are known to be susceptible to hydrogen embrittlement, via a mechanism commonly referred to as hydrogen-induced stress cracking...

... loading operations. The aging mechanisms considered for zirconium-based cladding include hydride reorientation and hydride-induced embrittlement, delayed hydride cracking, thermal and athermal (low-temperature) creep, mechanical overload, oxidation, stress corrosion cracking, radiation embrittlement...

... ABSTRACT Hydrogen uptake during electrochemical metal plating of high strength steels can cause severe embrittlement depending on the plating parameters. In situ hydrogen permeation measurements have been performed during electrochemical deposition of ZnNi coatings on 100 µm membranes of high...

... ABSTRACT Mercury is a naturally occurring component present in varying concentrations in natural gas fields all over the world. Liquid metal embrittlement (LME) involves penetration of a liquid metal into a solid metal that leads to brittle fracture. For this reason, a test program...

... ABSTRACT Nickel steels ASTM A353 and A553 (9% Nickel) and ASTM A203 Gr. E (3½% Ni) were studied for environmental cracking resistance using laboratory slow strain rate and constant load tests. Potential cracking mechanisms included mercury liquid metal embrittlement (Hg LME), hydrogen...

... to 30 hours depending on the thickness of the material. Stress relief is required for steels above Rockwell C 35 to prevent stress corrosion cracking (hydrogen embrittlement) during electroplating. Again, this illustrates the similarities between metals and non-metals. Pitting is a form of localized...

... INTRODUCTION ABSTRACT The zinc-containing primers, especially zinc silicate, are widely used on the carbon steel for both onshore and offshore environments. Their use on stainless steels is not recommended since there is a risk of liquid metal embrittlement by molten zinc in case of fire due...
