5. Precipitation Hardening (Kev laus)

Lub hom phiaj:

• Ua kom muaj zog los ntawm kev ua kom zoo precipitate

• Ua tau siab yield zog yam tsis muaj kev cuam tshuam ntau dhau

Txheej txheem:

• Cov tshuaj kho ntawm ~ 1040 ° C thiab quench

• Hnub nyoog ntawm 480-620 ° C rau ob peb teev

Siv Rau:

• 17-4PH (UNS S17400)thiab zoo sib xws alloys

• Aerospace, nuclear, thiab cov khoom muaj zog

Cov txiaj ntsig:

• Zoo heev zog-rau-qhov hnyav piv

• Zoo corrosion kuj

• Tsawg distortion piv rau martensitic hardening
