An accelerated corrosion test for electrodeposits.

A fractographic term describing ductile fracture that occurs through the formation and coalescence of microvoids along the fracture path. The fracture surface of such a ductile fracture appears dimpled when observed at high magnification and usually is mo ...

A crystal that has a treelike branching pattern, being most evident in cast metals, slowly cooled through the solidification range.

(1) A solid solution of one or more elements in body-centered cubic iron. Unless otherwise designated (for instance, as chromium ferrite), the solute is generally assumed to be carbon. On some equilibrium diagrams, there are two ferrite regions separated ...

Improving paint adhesion on aluminum or aluminum alloys, mainly aircraft skins, by treatment with a solution of' chromic acid. Also called chromodizing or chromatizing. Not to be confused with chromating or chromizing.

Removal of dissolved mineral matter, generally from water.

A thin, inhibiting paint, usually chromate pigmented with a polyvinyl butyrate binder.

A coating consisting of' a compound of the surface metal, produced by chemical or electrochemical treatments of the metal. Examples include chromate coatings on zinc, cadmium, magnesium, and aluminum and oxide and phosphate coatings on steel. See also chr ...

The stress at which a material exhibits a specified deviation from proportionality of stress and strain. An onset of 0.2% is used for many metals.

Corrosion in which zinc is selectively leached from zinc-containing alloys. Most commonly found in copper-zinc alloys containing less than 83% copper after extended service in water containing dissolved oxygen; the parting of zinc from an alloy (in some b ...

(1) Permanently damaging a metal or alloy by heating to cause either incipient melting or intergranular oxidation. See also over-heating. (2) In grinding, getting the work hot enough to cause discoloration or to change the microstructure by tempering or h ...

Forming austenite by heating a ferrous alloy into the transformation range (partial austenitizing) or above the transformation range (complete austenitizing). When used without qualification, the term implies complete austenitizing.

See conductivity.

Cooking liquor from the kraft pulping process produced by recausticizing green liquor with lime.

A condition in which the interfacial tension between a liquid and a solid is such that the contact angle is 0

The condition of an electrode when the rate of anodic dissolution just balances the rate of cathodic plating.885

A metastable aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures below the pearlite range but above M

Corrosion that is accompanied by a flow of electrons between cathodic and anodic areas on metallic surfaces.

Same as strain hardening.

The absorption of carbon into a metal surface; may or may not be desirable.
