Kiválásos edzés (Precipitation / Age Hardening)

A kiválásos edzést bizonyos ötvözeteknél alkalmazzák a mechanikai szilárdság növelésére, például alumíniumötvözeteknél, nikkelbázisú ötvözeteknél és egyes rozsdamentes acéloknál. A folyamat három lépésből áll:

Oldáshőkezelés (Solution Heat Treatment)

Edzés (Quenching)

Korosítás (Ageing – természetes vagy mesterséges)

A fém belsejében finom kiválások keletkeznek, amelyek gátolják a diszlokációk mozgását, így növelve a szilárdságot.

Hőmérsékleti tartomány:

  • Oldáshőkezelés: 450–550 °C
  • Korosítás: 100–200 °C

Használt ipari kemencetípusok:

  • Elektromos kamrakemence
  • Vákuumkemence
  • Szabályozott atmoszférás (Controlled Atmosphere) kemence

Alkalmazások:

Repülőgép-alkatrészek, szerkezeti elemek, nyomástartó edények
