A process of shock cooling thermoplastic materials from the molten state. Can be gradient or consistent cooling.

A compartment in a rod rolling operation where quenching is controlled to produce the characteristics necessary for the finished product.

The cooling of a heated metal through its transformation range, usually by immersing it in a liquid such as oil, water, molten salt or lead. Quenching is an integral part of most processes for the hardening of steel. Except for gas, it is essential that the cooling medium be controlled at a specified temperature and the material be immersed until it has attained the quench temperature throughout its mass. See Patenting and Patenting, Lead. When applicable, the following more specific terms are used: direct quenching, fog quenching, hot quenching, interrupted quenching, selective quenching, spray quenching and time quenching.

A fracture resulting from thermal stresses induced during rapid cooling or quenching. The fracture could be caused by poor quenching fluid temperature control where the fluid may be too cold.

After austenitizing, steel rod is prequenched in a salt bath at a temperature just over the Ms point. It is then transformed in a second salt bath at a temperature around 510°C, both baths in tandem. Approximate isothermal transformation is said to take place, providing a fine even structure and, consequently, high tensile strength, higher ductility for a given strength and improved fatigue properties.

A category of cable extrusion head tooling that provides nearly instantaneous color changes. The tooling allows several extruders, each processing a different color material, to feed into head. Internal valves redirect the flow from one extruder to another to make either base color changes and/or stripe color changes.
