Aging, английский
- Spontaneous change in the physical properties of some metals, which occurs on standing, at atmospheric temperatures after final cold working or after a final heat treatment. frequently synonymous with the term " age-hardening."
- Another spelling of ageing
- The life-long process of growing older; not just a later life experience
- A metallurgical change in a metal alloy resulting in an increase in mechanical properties. this change can occur in some instances at room temperatures. more often its effects are increased by holding for specified lengths of time at elevated temperatures. also known as precipitation hardening.
- (1) the effect of long term environmental exposure on materials or components. (2) heat treatment method that alters material properties and microstructure because of the duration of time at ambient (natural aging) or elevated (artificial aging) temperature. aging is commonly applied to alloys after hot working, quenching from an elevated temperature or cold working. see also precipitation hardening.
