The chemical compositions of the solid and liquid metals affect the severity of embrittlement. The addition of third elements to the liquid metal may increase or decrease the embrittlement and alter the temperature region over which embrittlement is seen. Metal combinations which form intermetallic compounds do not cause LME.

Adsorption embrittlement is the embrittlement caused by wetting. Liquid metal embrittlement (LME) is the embrittlement caused by liquid metals. Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of atoms of metal, either solid or liquid, into the material. For example, cadmium coating on high-strength steel, which was ...
Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of metal, either solid or liquid, into the base material. Metal induced embrittlement occurs when metals are in contact with low-melting point metals while under tensile stress. The embrittler can be either solid or liquid (liquid metal embrittlement).
Corrosion during service in moist environments generates hydrogen, part of which may enter the metal as atomic hydrogen (H •) and cause embrittlement. Presence of a tensile stress, either inherent or externally applied, is necessary for metals to be damaged. As in the case of stress corrosion cracking, hydrogen embrittlement may also lead to ...
Some of the most popular failure models in this area are the micromechanical failure models, which combine the advantages of continuum mechanics and classical fracture mechanics. [1] Such models are based on the concept that during plastic deformation , microvoids nucleate and grow until a local plastic neck or fracture of the intervoid matrix ...
Liquid Metal may refer to: A liquid metal, which has a relatively low melting point, such as mercury, tin or lead; Any metal in a liquid state; Mercury, the only metal to be liquid at room temperature; Liquid metallic hydrogen; Liquidmetal, a type of metallic glass; Liquid Metal (Sirius XM), a radio channel
[5] [6] The action of either a tensile stress or a corrosive liquid alone would not be enough to cause failure, but in ESC the initiation and growth of a crack is caused by the combined action of the stress and a corrosive environmental liquid. These corrosive environmental liquids are called 'secondary chemical agents', are often organic, and ...
