Txoj cai ntawm Hardness txo

 

Cov pa roj carbon monoxide yog ib qho ntawm cov khoom tseem ceeb uas cuam tshuam rau lub hardness ntawm steel. Hauv cov hlau, cov pa roj carbon tuaj yeem tsim cov khoom sib txuam nrog cov hlau, ua kom muaj zog-txhim kho cov nyhuv. Thaum cov ntsiab lus ntawm cov pa roj carbon tsawg tsawg, cov khoom no - cov tshuaj ntxiv dag zog rau cov nyhuv tsis muaj zog. Piv txwv li, nyob rau hauv ib tug hlau - carbon alloy, carbon atoms yog embedded nyob rau hauv lub lattice gaps ntawm hlau atoms, uas yuav distort lub lattice thiab ua rau kom cov kev tiv thaiv rau dislocation zog, yog li ua rau hardness. Raws li cov ntsiab lus ntawm cov pa roj carbon tsawg, qhov degree ntawm lattice distortion yog txo, thiab dislocation txav tau yooj yim dua, thiab hardness ntawm cov hlau yuav txo.

 

Nyob rau tib lub sijhawm, cov pa roj carbon kuj tuaj yeem tsim cov carbides (xws li cementite ) nrog hlau thiab lwm yam khoom. Cov carbide no yog cov theem nyuaj hauv cov hlau. Thaum cov ntsiab lus ntawm cov pa roj carbon tsawg tsawg, cov carbides txo qis, thiab qhov feem pua ​​ntawm cov theem nyuaj hauv cov hlau raug txo, uas tseem yuav ua rau txo qis hauv hardness ntawm cov hlau.

 

Kev cuam tshuam rau Machinability

 

Txiav Machining: Qhov txo qis hauv hardness ua kom yooj yim rau kev txiav cov hlau. Piv txwv li, thaum lub sij hawm machining txheej txheem xws li tig, milling, los yog drilling, txiav tsis kam ntawm cov cuab yeej txiav yog txo. Rau cov hlau uas muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, qhov hnav ntawm cov cuab yeej txiav yuav qeeb dua, thiab qhov zoo ntawm lub tshuab ua haujlwm tau yooj yim dua. Vim hais tias qhov qis hardness txhais tau hais tias cov yas deformation ntawm cov hlau yog qhov yooj yim dua, thaum lub sij hawm txiav, cov txheej txheem ntawm cov chips yog smoother, thiab cov teeb meem xws li txiav - cov cuab yeej tawg vim yog cov hlau hnyav dhau los yog nce hauv qhov roughness. ntawm qhov machined yuav tsis tshwm sim.

Txoj Kev Machining: Nyob rau hauv txias - sib sau (xws li txias - khoov, txias - dov) los yog kub - sib sau (xws li kub - dabtsi yog khoov, kub - dov) txheej txheem, steel nrog txo hardness muaj zoo formability. Noj txias - dabtsi yog khoov raws li piv txwv, cov hlau uas muaj cov ntsiab lus ntawm cov pa roj carbon tsawg yuav tsum muaj zog dabtsi yog khoov thaum lub sij hawm khoov cov txheej txheem thiab tsis tshua muaj kev tawg. Qhov no yog vim qhov qis hardness ua rau cov hlau mus rau cov yas deformation smoothly thaum raug rau sab nraud quab yuam, hloov mus rau cov duab ntawm pwm, thiab yog li yooj yim dua ua rau ntau yam duab. Piv txwv li, thaum tsim ib co tsheb qhov chaw los yog lub tsev structural Cheebtsam nrog tshwj xeeb cov duab, low - hardness steel muaj ntau qhov zoo.
