Corrosion engineering

corrosion embrittlement

Materials science; Corrosion engineering

The severe loss of ductility of a metal resulting from corrosive attack, usually inter,granular and often not visually apparent.

torsional stress

Materials science; Corrosion engineering

The shear stress on a transverse cross section resulting from u twisting action.

critical flaw size

Materials science; Corrosion engineering

The size of a flaw (defect) in a structure that will cause failure at a particular stress level.

polarization resistance

Materials science; Corrosion engineering

The slope (dE/di) at the corrosion potential of a potential (E)/current density (i) curve. Also used to describe the method of measuring corrosion rates using this slope.

spalling

Materials science; Corrosion engineering

The spontaneous chipping, fragmentation, or separation of a surface or surface coating.

yield strength

Materials science; Corrosion engineering

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.

plane stress

Materials science; Corrosion engineering

The stress condition in linear elastic fracture mechanics in which the stress in the thickness direction is zero; most nearly achieved in loading very thin sheet along a direction parallel to the ...
