Penetration of liquid metals into solid metals and liquid metal embrittlement

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2004
Abstract For some solid metal–liquid metal couples that exhibit liquid metal embrittlement, penetration of the embrittling liquid metal along grain boundaries of the solid metal is observed. Penetration speed of liquid gallium into aluminum and that of mercury into silver and copper were measured by using thin evaporated films.

Liquid metal embrittlement

Journal of Materials Science, 1979
Liquid metal embrittlement is the reduction in the elongation to failure that can be produced when normally ductile solid metals are stressed while in contact with a liquid metal. This review describes its principal characteristics and the several models which have been advanced in attempts to explain the occurrence and different features of the ...

Embrittlement of zinc by liquid metals

Metal Science, 1979
AbstractThe liquid metal embrittlement (LME) of pure polycrystalline zinc in tension has been studied at different temperatures and strain rates. LME was observed with gallium, mercury, indium, and tin, as expected, but also with bismuth and cadmium, contrary to previous reports. At moderate strain rates, e.g.

Embrittlement by liquid metals

Progress in Materials Science, 1973
Abstract : The report gives a summary of the investigations performed under the general title, 'Embrittlement by Liquid Metals.' During the period of the report, an earlier investigation of the effects of second phases on the susceptibility of zinc-cadmium alloys to embrittlement by liquid mercury at ambient temperature was continued. The investigation

The occurrence of liquid-metal embrittlement

Physica Status Solidi (a), 1971
A study has been made of the fracture behavior of cadmium in liquid mercury and several liquid mercury solutions. It is shown that the degree of embrittlement induced in a solid metal can be significantly and predictably affected by incorporating selected embrittling elements in solution in the liquid-metal environment.

Failure by liquid metal induced embrittlement

Engineering Failure Analysis, 1994
Abstract Liquid metal induced embrittlement (LMIE) refers to the loss of ductility of normally ductile metals and alloys when stressed whilst in contact with a liquod metal. This paper describes the characteristics of LMIE with particular emphasis on how these may assist in the process of failure analysis and presents the distinctive features of LMIE

Liquid Metal Embrittlement

1968
Liquid metal embrittlement is a generic term which refers to at least three distinctly different phenomena. The type of embrittlement which has received most attention in recent years appears to arise from a process in which atoms of the liquid adsorb preferentially at sites of high stress concentration, leading to a reduction in cohesive energy, and ...

EMBRITTLEMENT OF METALS BY ORGANIC LIQUIDS

1963
Abstract : The published literature on the subject is reviewed. The essential details of reduced fatigue life of steel in the presence of certain polar liquids discovered by Karpenko are confirmed. Studies on polar liquids and solutions were expanded to include a wider variety of long-chain organic species and a number of metalloorganic liquids.

Embrittlement of nanocrystalline nickel by liquid metals

Journal of Materials Science, 1994
Metallographic and fractographic tests of liquid metal embrittlement are performed for nanocrystalline Ni-Hg systems. It is shown that the behaviour of nanocrystalline nickel under these conditions is close to that of ordinary polycrystalline materials. The presence of a stage of subcritical crack growth is demonstrated.

Analysis of liquid metal embrittlement in materials

Mendeleev Communications, 2019
For studying initial surface damages in metals together with the effects caused by active media, the microsclerometry method has been combined with the electrochemical reduction of an active component on the tested surface. The method made it possible to detect a liquid metal embrittlement (LME) effect in the absence of a liquid metal phase.
