03659 LIQUID METAL EMBRITTLEMENT OF ALLOY 800 HYDROGEN UNIT PREHEAT TUBES

Product Number: 51300-03659-SG

ISBN: 03659 2003 CP

Author: D. W. Alley, D. J. Barker, M. W Mucek and S. A. Bradley

Publication Date: 2003

$20.00

Analysis of a 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 for the low temperature shift converter located downstream of the preheat tubes.

Analytical Method to Detect and Remediate Zinc Contamination of Austenitic Stainless Steels to avoid Liquid Metal Embrittlement

Product Number: 51323-18999-SG

Author: Adrian Valenzuela, Adalberto Toledo, Robert Leggat, Lake Barrett, James Kretzler

Publication Date: 2023

As construction of an industrial plant was nearing completion, it was realized that galvanized scaffolding was used during the erection of a large furnace. There was some concern about the possibility of zinc liquid metal embrittlement (LME) of the austenitic stainless-steel tubes. LME is the loss of ductility when a metal is in contact with liquid metal while under stress. Specifically, austenitic stainless steels are known to be susceptible to LME in the presence of liquid zinc which was implicated in the Flixborough Disaster where 28 people were killed in an industrial accident in 1974.

Liquid Metal Embrittlement in the Refining Industry – Case Histories and Common Prevention Practices

Product Number: 51323-18903-SG

Author: Cathleen Shargay, Shahab Soltaninia, Diana Basheva

Publication Date: 2023

$20.00

Liquid Metal Embrittlement (LME) phenomenon occurs when the certain molten metals wet the specific alloys, causing drastic ductility reduction that normally is associated with the formation of an intergranular crack that is sudden and brittle in nature. High tensile stress is also known to promote cracking; however, cracks may develop merely by contacting molten metal with a susceptible alloy as there is only a small amount of low-melting-point metal required to cause LME.

Mercury Liquid Metal Embrittlement Testing of Oil and Gas Production Alloys

Product Number: 51314-3993-SG

ISBN: 3993 2014 CP

Author: Stefanie Asher

Publication Date: 2014

$20.00

Liquid metal embrittlement (LME) involves penetration of a liquid metal into a solid metal that leads to brittle fracture. A test program was established to evaluate the susceptibility of various metallic materials to LME by mercury.

Testing Heavily Cold Formed 22Cr Duplex Stainless Steel Exposed to Liquid Mercury to Assess Liquid Metal Embrittlement Susceptibility

Product Number: 51324-20319-SG

Author: William Kovacs; Kristian Eriksen; Bjørn-Andreas Hugaas; Stian Hauger

Publication Date: 2024

$40.00

Existing literature suggests that while 22Cr may not be susceptible to Liquid Metal Embrittlement (LME) when exposed to mercury at typical engineering strains, heavily cold formed 22Cr materials may be susceptible. The LME susceptibility from mercury of cold formed UNS S31803 was tested using four-point bend, slow strain rate, and interrupted slow strain rate techniques, simulating a range of strains from primarily elastic deformation of as-produced / as-welded pipe to high plastic deformation of cold formed pipe. Specimens were selected from the base metal, the weld metal / heat affected zone, and from pre-strained material simulating cold forming. The testing was conducted in the presence of mercury (only) at both ambient temperature and 40 °C. The passive film was intentionally disrupted by scratching at the initiation of the tests. The results of this testing did not indicate evidence of LME for any of the material / environment conditions tested.
