Hardening
81surface hardening — ▪ metallurgy treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering… …
82Differential hardening — is a method used in forging swords and knives to increase the hardness of the edge without making the whole blade brittle. To achieve this, the edge is cooled more rapidly than the spine by adding a heat insulator to the spine before quenching.… …
83Cold hardening — is the physiological and biochemical process by which an organism prepares for cold weather. Plants Schematic of typical plant cell During the winter months, as the leaves fall off deciduous species and the temperature drops, the cold forces a… …
84Cryogenic hardening — is a cryogenic heat treating process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and …
