A single, solid, homogeneous crystalline phase containing two or more chemical species.

The occurrence of embrittlement in a material below the melting point of the embrittling species. See also liquid-metal embrittlement.

The component of either a liquid or solid solution that is present to a lesser or minor extent: the component that is dissolved in thesolution.

In chemistry,a homogeneous dispersion of two or more kinds of molecular or ionic species. Solution may be composed of any combination of liquids, solids, or gases, but they always consist of a single phase.

Heating an alloy to a suitable temperature, holding at that temperature long enough to cause one or more constituents to enter into solid solution, and then cooling rapidly enough to hold these constituents in solution.

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

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

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.

Waste waters containing fetid materials, usually sulfur compounds.

Release of contained gas in the vaccum of outer space. eg. rapid destructive expansion of plastics and similar materials.

Pitting resulting from ablation, outgassing or meteor contact.

The spontaneous chipping, fragmentation, or separation of a surtace or surface coating.

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

A coating process whereby thermally emitted electrons collide with inert gas atoms, which accelerate toward and impact a negatively charged electrode that is a target of the coating material. The impacting ions dislodge atoms of the target material, which ...

(1) Before finishing to final dimensions, repeatedly heating a ferrous or nonferrous part to or slightly above its normal operating, temperature and then cooling to room temperature to ensure dimensional stability in service. (2) Transforming retained aus ...

The reversible potential for an electrode process when all products and reactions are at unit activity on a scale in which the potential for the standard hydrogen half-cell is zero.

The unit of change in the size or shape of a body due to force. Also known as nominal strain.

Aging induced by cold working.

An increase in hardness and strength caused by plastic deformation at temperatures below the recrystallization range.

The time rate of straining for the usual tensile test. Strain as measured directly on the specimen gage length is used for determining strain rate. Because strain is dimensionless, the units of strain rate are reciprocal time.
