Direct Influence

 

Hardness nce: Silicon caij nws tus kheej muaj qee yam cuam tshuam rau kev ua kom lub zog ntawm cov hlau tom qab quenching. Thaum lub sij hawm quenching txheej txheem, silicon tuaj yeem ua kom lub zog ntawm cov khoom siv hauv cov hlau. Thaum silicon yaj mus rau hauv ferrite los ua ib qho kev hloov khoom siv, ib qho khoom ua kom muaj zog ntxiv yog tsim. Nws cuam tshuam qhov kev txav ntawm kev txav mus los thiab distorts cov siv lead ua lattice ntawm cov hlau, yog li ua rau lub zog ntawm cov hlau. Piv txwv li, nyob rau hauv ib co silicon - uas muaj cov cuab yeej steels, cov khoom no - kev ntxiv dag zog rau cov nyhuv ntawm silicon yuav ua rau lub hardness tom qab quenching siab tshaj li cov hlau zoo sib xws uas tsis muaj silicon rau ib yam dab tsi, uas yuav pab tau rau manufacturing ntau hnav - resistant cov cuab yeej.

 

Indirect Influence: Lub caij silicon hloov lub hardness los ntawm kev cuam tshuam lub microstructure transformation thaum lub sij hawm quenching txheej txheem. Silicon tuaj yeem nce qhov kub thiab txias ntawm cov hlau, kom cov txheej txheem austenitizing yuav tsum tau kub thiab lub zog. Qhov no yuav ua rau cov qauv zoo dua thiab zoo dua martensite tsim tom qab quenching thiab txias. Piv nrog cov qauv martensite ntxhib, cov qauv zoo thiab cov qauv martensite muaj zog dua thiab muaj zog. Vim hais tias cov nplua martensite muaj ntau thaj tsam ntawm cov nplej, nws lub peev xwm los cuam tshuam cov kev txav ntawm cov dislocations muaj zog, yog li tag nrho cov hardness ntawm cov hlau yog nce.

Kev cuam tshuam thaum lub sij hawm Tempering

 

Txhim kho Tempering Stability: Silicon kuj muaj ib qho tseem ceeb ntawm cov hardness ntawm steel tom qab tempering. Nws tuaj yeem txhim kho tempering stability ntawm steel, uas yog, thaum lub sij hawm tempering txheej txheem, silicon - uas muaj steel muaj peev xwm tiv taus qhov kev xav ntawm hardness txo. Thaum lub sij hawm tempering, carbon atoms yuav precipitate los ntawm supersaturated martensite los tsim carbides, thiab cov txheej txheem no yuav ua rau txo qis hardness ntawm hlau. Txawm li cas los xij, cov khoom siv silicon yuav ua rau qeeb ntawm kev loj hlob ntawm carbide aggregation. Piv txwv li, nyob rau hauv qee lub caij nplooj ntoos hlav steels, thaum lub tempering kub yog nyob nruab nrab ntawm 400 - 500 degree, cov aggregation tus nqi ntawm carbides nyob rau hauv steels nrog ib tug ntau dua silicon ntsiab lus yog ho qis dua nyob rau hauv steels tsis muaj silicon los yog muaj ib tug tsawg silicon ntsiab lus. Qhov no ua rau silicon - muaj cov hlau kom muaj zog dua tom qab tempering, tswj lawv cov kev txwv tsis pub elastic thiab lub zog zoo, thiab muaj txiaj ntsig zoo rau kev tsim cov khoom ua haujlwm siab thiab lwm qhov chaw uas xav tau kom muaj qee qhov hardness tom qab tempering.
