Reduction in mechanical properties of a metal as a result of local penetration of solder along grain boundaries.

The swelling or bubbling of a coating usually because of heating (term currently used in space and fire protection applications).

Concentration of a solution expressed in moles of solute divided by 1000 g of solvent.

See electrical resistivity.

Ratio of the depth of the deepest pit resulting from corrosion divided by the average penetration as calculated from weight loss.

(1) Decomposition or alteration of a chemical substance by water. (2) In aqueous solutions of electrolytes, the reactions of cations with water to produce a weak base or of anions to produce a weak acid.

The ability of a metal to absorb energy and deform plastically before fracturing.

Same as hydrogen embrittlement.

Water that is free of magnesium or calcium salts.

Changes in contour or discontinuities in structure that cause local increases in stress.

See transgranular.

Stress-corrosion cracking in which the cracking occurs along grain boundaries.

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

Threshold stress-intensity factor for stress-corrosion cracking. The critical plane-strain stress intensity at the onset of stress-corrosion cracking under specified conditions.

The severe loss of ductility or toughness or both, of a material, usually a metal or alloy. Many forms of embrittlement can lead to brittle fracture. Many forms can occur during thermal treatment or elevated temperature service (thermally induced embrittl ...
