1, Ua ntej, txoj kev kho cua sov.
Cov kev kho cua sov sib txawv tuaj yeem xaiv raws li cov khoom sib txawv thiab lub hom phiaj.
quenched thiab tempered steel: high-temperature tempering (500-650 degree)
Caij nplooj ntoos hlav steel: tempered tom qab quenching ntawm nruab nrab kub (420-520 degree)
Carburizing steel: tom qab carburizing quenching thiab qis-kub tempering (150-250 degree)
Nrog rau qhov nce ntawm tempering kub, lub zog ntawm cov pa roj carbon tsawg thiab nruab nrab carbon (alloy) steels tom qab martensitic quenching txo, thaum lub plasticity thiab toughness nce. Txawm li cas los xij, vim muaj cov ntsiab lus sib txawv ntawm cov pa roj carbon tsawg thiab nruab nrab, qhov cuam tshuam ntawm tempering kub yog txawv. Yog li ntawd, txhawm rau kom tau txais cov khoom zoo txhua yam, cov hauv qab no tuaj yeem raug coj los ua raws.
(1) Xaiv cov pa roj carbon tsawg (alloy) steel thiab temper nws ntawm qhov kub qis dua 250 degree tom qab quenching kom tau txais cov pa roj carbon tsawg. Txhawm rau txhim kho qhov hnav tsis kam ntawm cov hlau no, tsuas yog txhim kho cov ntsiab lus carbon ntawm txhua txheej txheej, uas yog, nto carburizing,
Feem ntau hu ua carburized structural steel.
(2), siv cov pa roj carbon siab, quenched tom qab kub siab (500-650 degree) tempering (uas yog, hu ua quenching thiab tempering kev kho mob), kom nws muaj peev xwm nyob rau hauv cov ntaub ntawv ntawm high plasticity, muaj zog txaus. , feem ntau hu ua hom hlau no rau quenching thiab tempering steel. Yog tias koj xav tau cov yas muaj zog, thiab xav kom txo cov yas thiab cov tawv nqaij, qhov kub thiab txias ntawm cov kub uas muaj cov pa roj carbon tsawg tuaj yeem siv tau, ces qhov hu ua "ultra-high-strength steel".
(3), carbon cov ntsiab lus ntawm nruab nrab carbon thiab siab carbon steel (xws li 60,70 steel) thiab ib co high carbon steel (xws li 80,90 steel), yog siv los tsim springs, thiaj li yuav xyuas kom meej siab elastic txwv, yield. txwv, thiab qaug zog txwv, siv quenching tempering.
2, Ob, titanium alloy cua sov txheej txheem:
(1) Kev ntxhov siab nyem annealing: lub hom phiaj yog txhawm rau tshem tawm lossis txo cov kev ntxhov siab uas tshwm sim hauv cov txheej txheem ua haujlwm. Tiv thaiv cov tshuaj erosion thiab txo deformation nyob rau hauv ib co corrosive ib puag ncig.
(2) Ua kom tiav annealing: lub hom phiaj yog kom tau zoo toughness, txhim kho kev ua tau zoo, ua kom haum rau reprocessing, thiab txhim kho stability ntawm qhov loj thiab lub koom haum.
(3) kev kho mob thiab kev laus: txhawm rau txhim kho nws lub zog, titanium alloy, thiab ruaj khov titanium alloy tsis tuaj yeem txhim kho los ntawm kev kho cua sov, tsuas yog annealing hauv ntau lawm. ntxiv rau titanium alloys thiab metastable titanium alloys uas muaj cov theem me me tuaj yeem ua kom muaj zog ntxiv los ntawm kev daws teeb meem thiab kev laus.
Tsis tas li ntawd, txhawm rau ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom ua haujlwm, kev lag luam kuj tseem siv ob chav annealing, isothermal annealing, kev kho cua sov, kev kho cua sov deformation, thiab lwm yam txheej txheem hlau kub-kho.
