Having an affinity for water. Contrast with hydrophobic.

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

Between crystals or grains. Also called intercrystalline. Contrast with transgranular.

A plot of r urrent density versus electrode potential for a specific electrode-electrolyte combination.

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

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

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

(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.

Same as hydrogen embrittlement.

Water that is free of magnesium or calcium salts.

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 ...
