See galvanostatic.

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.

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 hydrogen embrittlement.

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

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

See hydrogenembriltlement.

Aging induced by cold working.

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

Deep internal cracks caused by hydrogen.

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

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

Perforation of material in outer space resulting from meteor strikes.

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

See hydrogen embrittlement.

See intergranular corrosion.

Water that is free of magnesium or calcium salts.

Changes in contour or discontinuities in structure that cause local increases in stress.

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.
