Hardening means making a material, particularly a metal, physically harder, and includes particular cases such as:
- Hardening (metallurgy), the strengthening of metal alloys by heat treatment
- Case hardening, the process of hardening the surface of a metal by infusing elements into the material's surface forming a thin layer of a harder alloy
- Air-hardening steel
- Cryogenic hardening
- Differential hardening
- Diffusion hardening
- Fire hardening
- Induction hardening
- Laser hardening
- Precipitation hardening
- Quenching
- Shock hardening
- Work hardening, also called strain hardening or cold working
- Strain hardening exponent, a materials constant used in calculations regarding work hardening
It also has the metaphorical meaning of making something more resistant to some threat:
- Hardening (botany) or cold hardening, the process by which a plant survives freezing temperatures
- Hardening (computing), the process of securing a system
- Intellectual property hardening
- Target hardening, making a military or civilian installation resistant to armed attack
- Radiation hardening, making a component or installation resistant to ionizing radiation
- g-hardening, protection of something against high g-force due to acceleration
- Windows Service Hardening, protection of Microsoft Windows services
It may also mean:
- Absorption hardening, in nuclear engineering, an increase in the average energy of neutrons by absorption of those of lower energy
- Hardening of the arteries
