patenting

[′pat·ənt·iŋ]
(metallurgy)
A process used in the production of high-strength steel wire containing 0.35-0.85% carbon, in which the wire is heated to above the transformation temperature, then quenched in molten lead or molten salt, or cooled in air.

Patenting

 

a heat treatment of steel whereby sorbite, which is a lamellar microstructure of ferrite and cementite, is produced. Patenting usually includes the following steps: austenitizing by heating to 870°-950°C, isothermal transformation of the supercooled austenite in molten salt or lead at 450°-550°C, and cooling with water or in air. Several new types of patenting have been developed—for example, stepwise patenting and rimming layer patenting. Patenting provides high strength and ductility of products (usually wire), which are cold-worked from patented billets.
