Resin formed from reactions involving furfuryl alcohol alone or in combination with other constituents.

Cracking or fracturing that occurs through or across a crystal or grain. Also called transcrystalline cracking. Contrast with intergranular cracking.

See intergranular corrosion.

Resin formed by condensation of polybasic and monobasic acids with polyhydric alcohols.

A specimen that is notched and subjected to alternating stresses until a crack has developed at the root of the notch.

An atom, or group of atoms, that has gained or lost one or more outer electrons and thus carries an electric charge. Positive ions, or cations, are deficient in outer electrons. Negative ions, or anions, have an excess of outer electrons.

A metal whose luster has been reduced because of a surface film, usually a corrosion product layer.

The technique for maintaining a constant electrode potential.

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

An aggregate of iron or alloy carbides of essentially spherical shape dispersed throughout a matrix of ferrite.

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

The formation of isolated particles of corrosion products beneath the metal surface. This occurs as the result of preferential oxidation of certain alloy constituents by inward diffusion of oxygen, nitrogen, sulfur, and so forth.

Having an affinity for water. Contrast with hydrophobic.

Embrittlement of iron-chromium alloys (most notably austenitic stainless steels) caused by precipitation at grain boundaries of the hard, brittle intermetallic sigma phase during long periods of exposure to temperatures between approximately 560 and 980

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.

A plot of r urrent density versus electrode potential for a specific electrode-electrolyte combination.

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

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

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

Concentration of a solution expressed in moles of solute divided by 1000 g of solvent.
