Wrinkled markings on the surface of an ingot or casting from incipient freezing of the surface.

The process of melting out the expendable wax pattern from an investment mold by the application of heat, usually at temperatures less than 250°F (121)°C).

The maximum compressive, shear, tensile, or transverse strength of a sand mixture which has been dried at 220 to 230°F (105 to 110°C) and cooled to room temperature.

Ability of sand to flow into a flask and around a pattern; measured in the amount of sand falling through an inclined screen or slot.

A form of wear characterized by the presence of surface cavities, the formation of which is attributed to processes such as fatigue, local adhesion, cavitation or corrosion.

The displacement and/or detachment of metallic particles from a surface as a consequence of being exposed to flowing solids, fluids or gases.

Degree of resistance of a material to abrasion or wear.

Embrittlement during pickling due to absorption of hydrogen.

Hardening by aging, usually after rapid cooling or cold working.

A change in properties of metals and alloys which occurs slowly at room temperature and will proceed rapidly at higher temperatures. The change in properties is often, but not always, due to a phase c [..]
