Cov ntsiab lus carbon (C)

 

Ncaj Ncees Hardness: Carbon yog lub ntsiab tseem ceeb uas txiav txim siab qhov hardness ntawm hlau. Thaum lub sij hawm quenching txheej txheem, raws li cov ntsiab lus carbon nce, lub hardness ntawm quenched steel ho nce. Qhov no yog vim hais tias tom qab carbon dissolves rau hauv austenite, martensite yog tsim thaum lub sij hawm quenching txias, thiab hardness ntawm martensite mas nyob ntawm cov ntsiab lus carbon. Martensite yog ib qho supersaturated solid tov ntawm carbon nyob rau hauv - Fe. Qhov siab dua cov ntsiab lus carbon, qhov hnyav dua qhov lattice distortion ntawm martensite, uas cuam tshuam rau kev txav ntawm dislocations thiab nce hardness. Piv txwv li, lub hardness ntawm high - carbon steel (carbon cov ntsiab lus ntau dua 0.6%) tom qab quenching yog ntau dua li ntawm tsawg - carbon steel (carbon ntsiab lus tsawg dua 0.25%) . Lub T10 steel nrog cov ntsiab lus carbon txog li 1.0% tuaj yeem muaj qhov tawv ntawm li 62HRC (Rockwell hardness) tom qab quenching, thaum Q235 steel (cov ntsiab lus carbon txog 0.{{13} }}.20%) feem ntau muaj qhov tawv ntawm 30 - 40HRC tom qab quenching.

 

 

 

Manganese Khoom (Mn)

 

Txhim kho hardenability thiab nce hardness: Manganese tuaj yeem txhim kho cov tawv tawv ntawm cov hlau. Nws txo cov cua txias tseem ceeb ntawm cov hlau, ua kom muaj cov qauv martensite txawm tias qeeb qeeb. Piv txwv li, nyob rau hauv qis - carbon alloy steel 16Mn, qhov sib ntxiv ntawm manganese txhim kho cov hardenability ntawm cov hlau. Tom qab quenching, txij li cov qauv martensite txaus tuaj yeem tsim tau, nws qhov hardness yog nce, thiab qhov sib txawv ntawm hardness los ntawm qhov chaw mus rau cov tub ntxhais yog me me. Nyob rau tib lub sijhawm, manganese kuj tuaj yeem yaj rau hauv ferrite los tsim cov khoom siv - cov tshuaj ntxiv dag zog, ntxiv dag zog rau cov hlau.

 

Refine Grains thiab Optimize Hardness: Manganese tuaj yeem kho cov nplej rau qee yam. Thaum lub sij hawm quenching cua sov txheej txheem, nws muaj peev xwm inhibit qhov kev loj hlob ntawm austenite nplej. Cov nplej zoo yuav tsim cov qauv zoo martensite tom qab quenching, thiab cov qauv no muaj zog dua thiab muaj zog. Vim hais tias cov nplua-grained ciam teb tuaj yeem cuam tshuam qhov kev txav ntawm cov dislocations, lub hardness ntawm cov hlau yog optimized.

Vanadium Element (V)

 

Refine Grains thiab nce hardness: Vanadium yog ib qho muaj zog carbide - tsim cov khoom thiab tuaj yeem tsim tau zoo, dispersed carbides hauv steel. Thaum lub sij hawm quenching cua sov txheej txheem, cov carbides tuaj yeem tiv thaiv kev loj hlob ntawm austenite nplej, ua rau cov hlau kom tau txais cov qauv zoo martensite tom qab quenching, yog li ua kom cov tawv tawv. Piv txwv li, nyob rau hauv 50CrVA steel, muaj vanadium ua rau cov hlau muaj ib tug ntau yam thiab zoo martensite qauv tom qab quenching (lub quenching kub yog hais txog 860 - 880 degree, nrog roj - txias), thiab lub hardness yog ho ntau dua. dua li cov hlau zoo sib xws uas tsis muaj vanadium.

 

Secondary Hardening kom muaj zog hardness: Thaum lub sij hawm tempering, vanadium carbides yuav rov - yaj thiab disperse thiab precipitate, ua ib tug thib ob hardening nyhuv. Thaum lub tempering kub nce mus rau ib tug tej yam ntau yam (txog 550 - 600 degree), qhov thib ob hardening tshwm sim yuav ua rau kom lub hardness thiab lub zog ntawm cov hlau dua. Qhov no ua rau vanadium - muaj cov hlau kom ua tau raws li qhov yuav tsum tau ua ntawm kev tsim cov khoom siv nrog cov hardness siab thiab siab zog tom qab tsim nyog quenching thiab tempering, xws li high-kev ua tau zoo springs thiab cov khoom tseem ceeb.
