Solid - daws Strengthening kom nce hardness

 

Phosphorus tuaj yeem ua lub luag haujlwm ntawm cov khoom siv - cov tshuaj ntxiv dag zog hauv carbon steel. Thaum phosphorus yaj nyob rau hauv ferrite, nws yuav ua rau lub lattice ntawm ferrite distort. Vim hais tias qhov loj ntawm phosphorus atoms txawv ntawm cov hlau atoms, tom qab nws nkag mus rau hauv ferrite lattice, nws yuav cuam tshuam nrog cov txheej txheem tsis tu ncua ntawm cov hlau atoms thiab ua rau cov kab mob hauv zos hauv cov lattice.

 

Qhov no lattice distortion yuav impeds lub txav ntawm dislocations. Dislocations yog ib qho tsis xws luag hauv cov ntaub ntawv crystalline, thiab kev txav ntawm dislocations yog ib qho tseem ceeb mechanism rau cov ntaub ntawv los tsim cov yas deformation. Thaum lub zog ntawm dislocations yog hindered, cov khoom yog tsis tshua muaj mus undergo yas deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, yog li qhia ib tug nce nyob rau hauv hardness.

 

Txawm li cas los xij, txawm hais tias cov khoom siv - cov tshuaj ntxiv dag zog ntawm phosphorus tuaj yeem ua kom tawv tawv, nws tseem yuav txo cov tawv tawv ntawm cov hlau. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas tsis tshua muaj kub, qhov txias - brittleness tshwm sim los ntawm phosphorus yuav deteriorate cov kev ua tau zoo ntawm hlau.

 

Tsim Brittle Phases los cuam tshuam Hardness Distribution

 

Phosphorus kuj tseem tuaj yeem tsim cov theem nkig hauv carbon hlau. Hauv thaj tsam ntawm cov nplej, phosphorus yog qhov yooj yim rau kev cais tawm. Thaum cov ntsiab lus phosphorus siab heev, nws yuav tsim ib co nkig tebchaw nrog hlau thiab lwm yam ntsiab lus. Lub hav zoov ntawm cov nkig theem no yuav hloov lub microstructure ntawm hlau.

 

Ntawm qhov tod tes, lub hardness ntawm lub nkig theem yuav txawv ntawm cov matrix, uas yuav ua rau cov khoom tsis sib xws hardness faib rau hauv cov khoom. Nyob rau hauv cheeb tsam uas muaj cov theem brittle, lub hardness yuav nce los yog txo nyob rau hauv lub zos, nyob ntawm seb cov yam ntxwv ntawm lub brittle theem.

 

Ntawm qhov tod tes, cov theem nkig no yooj yim los ua qhov chaw tawg thaum raug rau sab nraud. Vim lawv cov brittleness, lawv tsis tuaj yeem cuam tshuam kev ntxhov siab los ntawm cov yas deformation zoo li cov matrix nrog zoo toughness. Yog li ntawd, thaum lub sij hawm tawg propagation txheej txheem, nws yuav cuam tshuam rau tag nrho cov hardness kuaj tau ntawm cov khoom thiab tej zaum yuav ua rau cov khoom tawg nyob rau hauv ib tug qis dua kev nyuaj siab, txo qhov tseeb hardness - hais txog kev ua tau zoo uas cov khoom yuav dais.

 

Comprehensive Influence ntawm cov ntsiab lus tswj ntawm Hardness

 

Hauv carbon steel, phosphorus feem ntau suav hais tias yog ib qho teeb meem, thiab nws cov ntsiab lus feem ntau yuav tsum tau tswj hwm ntawm qib qis (feem ntau tsawg dua 0.045%). Hauv cov ntsiab lus no, qhov cuam tshuam ntawm phosphorus ntawm hardness yog me me.

 

Thaum cov ntsiab lus phosphorus ntau tshaj ib qho kev txwv, nws cov kev tsis zoo ntawm hardness (xws li qhov txo qis hauv toughness tshwm sim los ntawm txias - brittleness, tawg los ntawm nkig theem, thiab lwm yam) yuav dhau lub hardness - nce cov nyhuv coj los ntawm nws cov khoom - tov ntxiv zog. . Lub sijhawm no, kev ua tau zoo ntawm cov khoom siv yuav deteriorate. Tsis yog tsuas yog hardness tis tsis yog - uniform, tab sis nws kuj yog ib qho kev puas tsuaj thaum lub sij hawm ua los yog siv. Piv txwv li, hauv kev tsim khoom ntawm qee qhov khoom siv uas xav tau ob qho tib si hardness thiab toughness, yog tias cov ntsiab lus phosphorus siab dhau lawm, nws yuav ua rau cov khoom tawg thaum raug rau qee qhov kev quab yuam sab nraud vim tias tsis muaj zog thiab tsis muaj zog, tsis muaj peev xwm. kom tau raws li qhov yuav tsum tau siv.
