The binding of an adsorbate to the surface of a solid by forces whose energy levels approximate those of condensation. Contrast with chemisorption.

A metallic coating obtained bydipping the base metal into a molten metal.

The part of the total carbon in steel or cast iron that is present in elemental form as graphite or temper carbon. Contrast with combined carbon.

The stress required to produce fracture in the plane of cross section, the conditions of loading being such that the directions of force and of resistance are parallel and opposite although their paths are offset a specified minimum amount. The maximum lo ...

Perforation of material in outer space resulting from meteor strikes.

Formation of isolated particles of corrosion products beneath a metal surface. This results from the prcferential reactions of certain alloy constituents to inward diffusion of oxygen, nitrogen, or sulfur.

Molten slag; in the pulp and paper industry, the cooking chemicals tapped from the recovery boiler as molten material and dissolved in the smelt tank as green liquor.

(1) An arbitrarily defined temperature that lies within the temperature range in which metal fracture characteristics (as usually determined by tests of notched specimens) change rapidly, such as from primarily fibrous (shear) to primarily crystalline (cl ...

Aging induced by cold working.

Coating containing a zinc powder pigment in an inorganic vehicle.

Corrosion occurring preferentially at grain boundaries, usually with slight or negligible attack on the adjacent grains. Also called intercrystalline corrosion.

See hydrogenembriltlement.

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

A tendency for some alloys to separate along grain boundaries when stressed ordeformed at temperatures near the melting point.Hot shortness is caused by a low-melting constituent, often present only in minute amounts,that is segregated at grain boundaries ...

See galvanostatic.

The current distribution in an electrolytic cell that is free of polarization.

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

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

The movement of ions through the electrolyte associated with the passage of the electric current. Also called transport or migration.

Deep internal cracks caused by hydrogen.
