Ua haujlwm tawv, hauv metallurgy, nce hauv cov tawv tawv ntawm cov hlau induced, txhob txwm los yog yuam kev, los ntawm hammering, dov, kos duab, lossis lwm yam txheej txheem ntawm lub cev. … Qhov laj thawj rau qhov zoo li qhov tsis zoo no nyob hauv cov qauv crystalline ntawm cov hlau.
Dab tsi yog qhov nyuaj hauv kev tshawb fawb?
Hardening yog txheej txheem metallurgical metalworking siv los ua kom tawv tawv ntawm cov hlau. Lub hardness ntawm ib tug hlau yog ncaj qha proportional rau lub uniaxial yield kev nyuaj siab ntawm qhov chaw ntawm lub imposed hom. Cov hlau tawv dua yuav muaj kev tiv thaiv ntau dua rau cov yas deformation dua li cov hlau tsis tshua muaj zog.
Puas ua haujlwm tawv zoo lossis phem?
Cold ua hauj lwm / lim hardening yog dav siv los ua kom cov neeg kho tshuab yam ntxwv ntawm ntau alloys. Hardening muab lawv cov khoom tseem ceeb ntawm toughness thiab shaping peev xwm.
Dab tsi yog qhov txawv ntawm kev ua haujlwm txias thiab ua haujlwm tawv?
Txoj tawv tawv, tseem hu ua kev ua haujlwm txias lossis ua haujlwm tawv, yogtxheej txheem uas cov hlau tau ua kom muaj zog thiab nyuaj dua los ntawm kev deformation mus tas li. … Tempering yog hom thiab tus nqi ntawm kev ua rau cov hlau thaum nws nyob ntawm lub zeb, suav nrog kev kho cua sov thiab ua haujlwm txias.
Lub hom phiaj ntawm kev ua haujlwm tawv yog dab tsi?
Kev ua haujlwm tawv tawv yog ib qho kev pabcuam tus kheej, tsim qauv tsim los pab cov neeg mob rov qab mus rau lawv qhov kev ua haujlwm ua ntej raug mob hauv qhov chaw nyab xeeb thiabraws sijhawm. Nws lub hom phiaj los pab cov neeg mob rov tau txais lawv cov biomechanical, hlab plawv, metabolic, neuromuscular thiab psychosocial functions nrog rau lawv cov hauj lwm.
