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 ...

Plastic deformation by the irreversible shear displacement (translation) of one part of a crystal relative to another in a definite crystallographic direction and usually on a specific crystallographic plane. Sometimes called glide.

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.

The technique for varying the potential of an electrode in a continuous manner at a preset rate.

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 ...

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

See hydrogen embrittlement.

Perforation of material in outer space resulting from meteor strikes.

Aging induced by cold working.

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.

Deep internal cracks caused by hydrogen.

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

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.

See galvanostatic.

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 ...

Coating containing a zinc powder pigment in an inorganic vehicle.

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

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

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

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