Influence rau Toughness

 

Txias - Brittleness Phenomenon: Phosphorus yog lub ntsiab tseem ceeb uas ua rau txias - brittleness ntawm carbon hlau. Nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, phosphorus sib cais ntawm cov ciam teb, uas txo cov toughness ntawm carbon hlau. Raws li qhov kub thiab txias, qhov sib sau ntawm phosphorus atoms ntawm cov ciam teb yuav txo tau lub zog ntawm cov ciam teb. Thaum siv lub zog sab nraud, cov kab nrib pleb yog qhov tshwm sim ntawm cov ciam teb ntawm cov qoob loo thiab kis tau sai, ua rau cov pa roj carbon monoxide ua rau qhov kub thiab txias. Piv txwv li, rau qee cov pa roj carbon - steel structural Cheebtsam siv nyob rau hauv cov cheeb tsam txias, yog hais tias cov ntsiab lus phosphorus siab, brittle fractures yuav tshwm sim thaum lub caij ntuj no kub yog tsawg.

 

Kev txo qis ntawm cov yas deformation muaj peev xwm: Lub xub ntiag ntawm phosphorus yuav cuam tshuam qhov kev txav ntawm kev txav mus los. Qhov no tsis tsuas yog cuam tshuam rau hardness tab sis kuj txo cov yas deformation muaj peev xwm ntawm carbon steel. Hauv kev sim tensile, carbon steel nrog cov ntsiab lus phosphorus siab tuaj yeem tawg ntawm qhov qis qis thiab tsis tuaj yeem ua rau cov yas deformation loj xws li carbon steel nrog cov ntsiab lus phosphorus ib txwm. Qhov no yog vim hais tias lub zog ntawm dislocations yog ib qho tseem ceeb mechanism rau cov ntaub ntawv los tsim cov yas deformation, thiab cov lattice distortion thiab dislocation obstruction los ntawm phosphorus deteriorate lub toughness ntawm cov khoom.

 

Kev cuam tshuam ntawm Weldability

 

Phosphorus muaj kev cuam tshuam tsis zoo thaum lub sij hawm vuam txheej txheem. Nyob rau hauv tshav kub - cuam tshuam cheeb tsam ntawm vuam, phosphorus yog nquag mus cais, ua rau lub brittleness ntawm cheeb tsam no. Txij li cov txheej txheem vuam ua rau muaj kev ntxhov siab thermal, lub nkig cua sov - cuam tshuam cheeb tsam muaj feem ntau yuav tsim cov kab nrib pleb nyob rau hauv qhov kev txiav txim ntawm thermal stress. Nyob rau tib lub sijhawm, phosphorus tseem yuav txo qhov toughness ntawm vuam hlau, txo qhov zoo ntawm cov welded sib koom. Piv txwv li, thaum lub sij hawm phau ntawv arc vuam txheej txheem ntawm carbon steel, yog hais tias cov phosphorus cov ntsiab lus ntawm cov hlau nws tus kheej yog siab, lub welded sib koom yuav tawg los ntawm tshav kub - cuam tshuam cheeb tsam los yog welding thaum raug rau sab nraud quab yuam.

 

 

Influence ntawm Machinability

 

Qhov tsim nyog tus nqi ntawm phosphorus tuaj yeem txhim kho kev ua haujlwm ntawm carbon hlau. Qhov no yog vim muaj phosphorus yuav ua rau cov chips yooj yim tawg. Thaum lub sij hawm txiav, qhov nce brittleness ntawm cov khoom tshwm sim los ntawm phosphorus ua rau cov chips feem ntau yuav tawg mus rau hauv me me pieces tom qab ncav cuag ib tug ntev ntev, txo qhov teeb meem ntawm chips winding nyob ib ncig ntawm lub txiav cuab tam, yog li txhim kho cov txiav efficiency. Txawm li cas los xij, thaum cov ntsiab lus phosphorus siab dhau lawm, vim tias cov khoom siv brittleness ntau dhau, qhov zoo ntawm lub workpiece yuav poob qis thaum txiav, thiab qhov tsis xws li ntug chipping yuav tshwm sim.

 

Kev cuam tshuam ntawm Corrosion Resistance

 

Phosphorus muaj qee yam cuam tshuam rau corrosion kuj ntawm carbon steel. Feem ntau hais lus, phosphorus tuaj yeem tsim cov phosphating zaj duab xis rau saum npoo ntawm cov hlau. Cov phosphating zaj duab xis no tuaj yeem ua lub luag haujlwm cais tawm, tiv thaiv corrosive media xws li oxygen thiab dej los ntawm kev sib cuag nrog cov pa roj carbon - steel matrix, yog li txhim kho corrosion kuj ntawm carbon steel rau qee yam. Txawm li cas los xij, yog tias cov ntsiab lus phosphorus siab dhau lawm, nws yuav ua rau muaj qhov tsis sib xws ntawm phosphating zaj duab xis lossis tsim ntawm qee theem uas yooj yim corroded hauv cov khoom, es tsis txhob txo cov corrosion kuj. Piv txwv li, nyob rau hauv ib co carbon - steel kav nrog ib tug tej yam yuav tsum tau rau corrosion kuj, ib tug tsim nyog tus nqi ntawm phosphorus yuav pab tau cov kav dej tiv thaiv corrosion, tab sis kev tswj tsis zoo ntawm phosphorus cov ntsiab lus yuav ua rau kom cov corrosion ntawm cov kav dej.
