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

Removing surface oxides from metals by chemical or electrochemical reaction. Pickling is the removal of any high temperature scale and any adjacent low chromium layer of metal from the surface of stainless steel by chemical means. Where the steel has b ...

(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 ...

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.

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

Perforation of material in outer space resulting from meteor strikes.

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.

Coating containing a zinc powder pigment in an inorganic vehicle.

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.

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

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 ...

Aging induced by cold working.

See hydrogenembriltlement.

See galvanostatic.

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

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.

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

See intergranular corrosion.

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