A stress that causes an elastic body to deform (shorten) in the direction of the applied load. Contrast with tensile stress.

A change in any part of the corrosion system caused by corrosion.

A form of deterioration that is distributed more or less uniformly over a surface; See uniform corrosion.

Direct current supplied by a device employing a power source external to the electrode system of a cathodic protection installation.

(1) In heat treatment, to reheat hardened steel or hardened cast iron to some temperature below the eutectoid temperature for the purpose of decreasing hardness and increasing toughness. The process is also sometimes applied to normalized steel. (2) In to ...

The potential of an electrode measured with respect to a reference electrode or another electrode when no current flows to or from it.

The relative ability of a ferrous alloy to form martensite when quenched from a temperature above the upper critical temperature. Hardenability is commonly measured as the distance below a quenched surfsce at which the metal exhibits a specific hardness ( ...

The maximum cyclic stress value that a metal can with stand for a specified number of cycles or length of time in a given corrosive environment. See corrosion fatigue strength

An aqueous solution containing one gram equivalent of the active reagent in 1L of the solution.

Rapid cooling of metals (often steels) from a suitable elevated temperature. This generally is accomplished by immersion in water, oil, polymer solution, or salt, although forced air is sometimes used.

A general term used to imply that a part in service (1) has become completely inoperable, (2) is still operable but is incapable of satisfactorily performing its intended function, or (3) has deteriorated seriously, to the point that it has become unrelia ...

Threshold stress intensity for stress-corrosion cracking. The critical stress intensity at the onset of stress-corrosion cracking under specified conditions.

Corrosion that occurs under some coatings in the form of randomly distributed threadlike filaments.

Any of the elements of the halogen family, consisting of fluorine, chlorine, bromine, iodine, and astatine.

The face-centered cubic form of pure iron, stable from 910 to l400

(1) An organic compound in which atoms form more than one coordinate bond with metals in solution. (2) A substance used in metal finishing to control or eliminate certain metallic ions present in undesirable quantities.

Surface having a thin, tightly adhering, oxidized skin (from straw to blue in color), extending in from the edge of a coil or sheet.

A chemical process involving formation of a heterocyclic ring compound that contains at least one metal cation or hydrogen ion in the ring.

Progressive loss of original material from a solid surface due to continuing exposure to cavitation.

An index calculated from total dissolved solids, calcium concentration, total alkalinity, pH and solution temperature that shows the tendency of a water solution to precipitate or dissolve calcium carbonate.
