...ABSTRACT Zinc embrittlement is known as a kind of liquid metal embrittlement, a phenomenon where austenitic stainless steel and nickel alloy becomes brittle and/or cracks when it comes in contact with molten zinc. Zinc embrittlement can occur due to poor design and/or construction, but this study...

Analysis of hardness measurements in the heat affected zone (HAZ), liquid metal embrittlement readings (LME), and microimaging of the bond cross section...

...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 samples...

Galvanized Steel Fasteners Liquid Metal Embrittlement Stainless Steel Corrosion INTRODUCTION Liquid metal embrittlement is a phenomenon that promotes drastic loss of ductility in normally ductile alloys when in the presence of certain liquid metals. Liquid zinc is a known...

Abstract Liquid mercury can be a natural component of natural gas, condensate, and crude oil production streams, so the potential for liquid metal embrittlement (LME) of hydrocarbon...

... kinetics are too slow to completely remove all liquid Hg. Liquid Mercury Attack of Metals Mercury liquid metal embrittlement (Hg-LME) occurs when mercury in the liquid form contacts a susceptible metal. LME can be defined as brittle fracture of a solid metal under stress that occurs due...

... Mechanisms vs 9% Ni Steel 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...

... Liquid Metal Embrittlement As the name implies, mercury liquid metal embrittlement (Hg-LME) occurs when mercury in the liquid form contacts a susceptible metal. LME can be defined as brittle fracture of a solid metal under stress that occurs due to the intergranular penetration of a liquid metal...

...EXPERIMENTAL Two types of stainless steels were tested, which are AISI 321 and duplex stainless steel (type 2205). Tables 1 and 2 respectively show the chemical compositions and the mechanical properties of the both stainless steels. liquid metal embrittlement zinc silicate stainless steel...

...Abstract Failure analyses were performed on three fractured 6061-T6 Aluminum alloy turbo-expander wheels that were exposed to a mercury-bearing natural gas environment. This investigation showed that failure of the 6061 Al-alloy was due to corrosion attack by liquid metal embrittlement (LME...

...Abstract A failure analysis was conducted on a 1½ inch diameter UNS N08800 hydrogen unit preheat tube that failed in service. Based on chemical and metallographic analyses the failure was attributed to liquid metal embrittlement by zinc. The zinc source is thought to be the Cu/Zn catalyst...

.... It shows that there is localized plastic deformation in brittle failure induced by chemisorption of liquid metals. The reduction in ductility and fracture stress of many metals tested in certain liquid metal environments is generally known as liquid metal embrittlement (LME)^{[ 1 ]}. Many theories...

A detailed test program using the Slow Strain Rate Testing (SSRT) method has been conducted to identify the various parameters which could contribute to SCC. Results indicate that the Cu-Ni-Mn-Al alloy...

...Abstract The susceptibility of Alloys 400, 600, 200 and 800 to liquid metal embrittlement (LME), hydrogen embrittlement and stress corrosion cracking are in that order (most to least). Correlations exist, too, in the cracking mode, intergranular or transgranular. Accordingly, understanding LME...
