A term generally applied to paints to describe holidays, holes, and skips in a film. Also used to describe shrinkage in castings and weld.

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

Cracking that occurs in the weld metal. See also cold cracking, hot cracking, lamellar tearing, and stress-relief cracking.

Intergranular corrosion, usually of stainless steels or certain nickel-base alloys, that occurs as the result of sensitization in the heat-affected zone during the welding operation.

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

A substance that reduces the surface tension of a liquid, thereby causing it to spread more readily on a solid surface.

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

Zinc oxide: the powdery product of corrosion of zinc or zinc-coated surfaces.

Same as strain hardening.

The test or specimen electrode in an electrochemical cell.

Evidence of plastic deformation in structural materials. Also called plastic flow or creep. See also flow.

The first stress in a material, usually less than the maximum attainable stress, at which an increase in strain occurs without an increase in stress. Only certain metals - those that exhibit a localized, heterogeneous type of transition from elastic defor ...

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.

The stress level in a material at or above the yield strength but below the ultimate strength, i.e., a stress in the plastic range.

See electrokinetic potential.
