The liquor resulting from dissolving molten melt irom the kraft recovery furnace in water. See also kraft process and smelt.

The swelling or bubbling of a coating usually because of heating (term currently used in space and fire protection applications).

See hydrogen embrittlement.

Reduction in mechanical properties of a metal as a result of local penetration of solder along grain boundaries.

The technique for maintaining a constant electrode potential.

Discontinuities in ci coating (suchasporosity, cracks, gape. and similar Bawd) that allow areas of base metal to be exposed to any corrosive environment that contacts the coated surface.

See galvanostatic.

Cracking or fracturing that occurs between the grains or crystals in a polycrystalline aggregate. Also called intercrystalline cracking. Contrast with transgranular cracking.

See hydrogen embrittlement.

The component of either a liquid or solid solution that is present to a greater or major extent; the component that dissolves the solute.

Deep internal cracks caused by hydrogen.

Through or across crystals or grains. Also called intracrystalline or transcrystalline.

Electrode potential where half-cell reaction involves only the metal electrode and its ion.

Aging induced by cold working.

Corrosive attack that progresses preferentially along interdendritic paths. This type of attack results from local differences in composition, such as coring commonly encountered in alloy castings.

See intergranular corrosion.

In fatigue, the variation in the stress-intensity factor in cycle, that is, Kmax-Kmin.

See hydrogenembriltlement.

A gaseous environment containing hydrogen sulfide and carbon dioxide in hydrocarbon reservoirs. Prolonged exposure to sour gas can lead to hydrogen damage, sulfide-stress cracking, and/or stress-corrosion cracking in ferrous alloys.

The ability of a metal to absorb energy and deform plastically before fracturing.
