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.

Any metallic structure that is not intended as part of a cathodic protection system of interest.

See hydrogen embrittlement.

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

A buried item, such as junk steel or graphite rods, that serves as the anode for the cathodic protection of pipelines or other buried structures. See also deep groundbed.

Discontinuities in ci coating (suchasporosity, cracks, gape. and similar Bawd) that allow areas of base metal to be exposed to any corrosive environment that contacts the coated surface.

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

A process resulting in adecrease of the toughness or ductility of a metal due to the presence of atomic hydrogen. Hydrogen embrittlement has been recognized classically as being of two types. The first known as internal hydrogen embrittlement, occurs when ...

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

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

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

Perforation of material in outer space resulting from meteor strikes.

Coating containing a zinc powder pigment in an inorganic vehicle.

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

Aging induced by cold working.

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

Deep internal cracks caused by hydrogen.

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

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 ...
