Lub ntiaj teb tsis tshua muaj txiaj ntsig tuaj yeem txhim kho qhov tawv ntawm cov hlau cam khwb cia

Tshaj tawm Lub sijhawm: Tus Sau: Tus Sau Site Xyuas: 17144

Raws li peb txhua tus paub, ntxiv qhov tsim nyog ntawm cov khoom ntiaj teb tsis tshua muaj nqi rau cov khoom siv hlau yuav muaj qhov cuam tshuam zoo rau tus qauv thiab ua tiav ntawm cov khoom ntawd. Feem ntau tsis tshua muaj lub ntiaj teb tsis tshua muaj hlau nyob hauv steel ntxiv rau hauv 0.05% ~ 0.20%. Vim tias qhov sib piv ntawm atomic radii ntawm lub ntiaj teb tsis tshua muaj hlau mus deb tshaj 15%, thiab qhov sib txawv hauv electronegativity ntawm lub ntiaj teb tsis tshua muaj thiab cov hlau yog loj heev, cov no tsis zoo rau kev tsim cov khoom sib xyaw, yog li solubility ntawm ntiaj teb tsis tshua muaj hlau. yog tsawg heev. Feem ntau cov khoom ntiaj teb uas tsis tshua muaj nyob hauv cov hlau muaj nyob hauv daim ntawv ntawm cov tebchaw ntiaj teb, tshwj xeeb tshaj yog lub ntiaj teb tsis tshua muaj kab thiab oxides tsawg kawg.

Xi'an Aeronautical Vocational thiab Technical College tau ua tiav kev tshawb fawb txog qhov cuam tshuam ntawm kev ntxiv cov khoom ntiaj teb tsis tshua muaj los txhawm rau hlau ntawm nws cov qauv thiab kev ua haujlwm. Lawv siv ZG35CrMnSi nrum hlau ua cov khoom xeem, thiab lub ntiaj teb tsis tshua muaj kev sib xyaw tau siv tau yog muaj sib xyaw tsawg hauv ntiaj teb. Txiav txim siab tias cov khoom ntsuas muaj qee tus nqi ntawm leej faj Thiab poob thaum ntxiv cov khoom hauv ntiaj teb tsis tshua muaj, qhov ntau ntawm lub ntiaj teb tsis tshua muaj ntxiv yog 0.23%~ 0.38%, qhov ntxiv no hais txog tag nrho cov nyiaj tsawg hauv ntiaj teb ntxiv rau cov hlau yaj thaum lub sij hawm zom. Sib piv cov qauv thiab kev ua tau zoo ntawm ob pawg ua piv txwv nrog thiab tsis muaj lub ntiaj teb uas tsis tshua muaj. Hlau casting yog smelted nyob rau hauv nruab nrab zaus induction rauv, thiab casting yog npaj los ntawm peev casting. Tom qab ntawd cov ntawv xeem yog rhuab mus rau 900 ° C + 670 ° C rau cov cua txias, thiab tom qab ntawd rhaub kom txog 890 ° C rau quenching hauv roj; ces 570 ~ 630 ° C hluav taws.

Kev sib piv cov txiaj ntsig tau qhia pom tias lub ntiaj teb tsis tshua muaj qhov cuam tshuam me me rau lub zog ntawm cov hlau cam khwb cia, tab sis nws muaj qhov cuam tshuam loj rau qhov tawv ntawm cov hlau cam khwb cia. Qhov kev cuam tshuam toughness tau nce ntxiv los ntawm 43%, thiab lub siab elongation yog nce li 13.3%. Microstructure kev tshuaj xyuas pom tias qhov txias ntawm sorbite ntawm cov qauv hlau tsis muaj lub ntiaj teb tsis tshua muaj cov ntsiab lus yog ntxhib, thiab nws qhov loj me me yog li 5; ntawm lawv, cov qog grey yog MnS suav nrog, uas tsis faib tawm rau tag nrho qhov chaw tshuaj xyuas. Feem ntau, cov morphology ntawm MnS feem ntau yog kaum. Cov qauv piv txwv ntawm cov hlau cam khwb cia nrog lub ntiaj teb tsis tshua muaj lub ntiaj teb yog qhov ua tau zoo thiab ua kom lub cev zoo nkauj, thiab qhov loj me me yog li ntawm 8-9. Nws qhia tau hais tias cov qauv ntawm cov hlau cam tuaj yeem ua kom zoo dua tom qab ntxiv cov khoom ntiaj teb tsis tshua muaj.

Ib qho ntxiv, tom qab ntxiv cov khoom hauv ntiaj teb tsis tshua muaj, qhov ua kom tsis muaj zog ntawm cov hlau tsis pom tseeb, tab sis nws muaj kev cuam tshuam ntau dua ntawm kev hloov pauv ntawm MnS. Thaum lub ntiaj teb tsis tshua muaj lub ntsiab lus tsis raug ntxiv, MnS hauv cov hlau muaj qhov zoo li ntawm cov duab sib txuas lossis cov nplov nrog cov npoo thiab cov fab; tom qab ntxiv qhov tsis tshua muaj tshwm sim hauv ntiaj teb, sulfide yog kwv yees li ib puag ncig, thiab kev faib tawm tau sib cais sib piv rau cov piv txwv yam tsis muaj lub ntiaj teb tsis tshua muaj ntsiab, tab sis tsuas yog nyob hauv qee qhov chaw Koj tuaj yeem pom sawb lossis thaiv sulfide suav nrog. Ntawm qhov tawg ntawm qhov piv txwv yam tsis muaj lub ntiaj teb tseem ceeb, MnS tau mloog zoo thiab dendritic. Qhov tawg ntawm MnS cov cheeb tsam mas feem ntau yog qhov kev sib tsoo me, thiab qhov kev sib tsoo luv ntawm lwm qhov tuaj yeem pom hauv zos.

Hauv qhov piv txwv nrog cov khoom hauv ntiaj teb tsis tshua muaj, qhov tawg yog ductile transgranular fracture. Txawm hais tias nyob hauv thaj chaw uas sulfides tau mloog zoo, cov hlau matrix tseem yog ductile transgranular puas. Cov hlau cam khwb cia ntxiv nrog cov khoom hauv ntiaj teb tsis tshua muaj tshem tawm cov dendritic sulfides thiab hloov pauv mus rau hauv cov tog raj kheej lossis cov pas nrig tsis sib thooj thiab tsis tshua muaj lub ntiaj teb sulfides loj heev, uas muaj txiaj ntsig zoo rau kev txhim kho tawv.

Cov kev tshawb fawb tau taw qhia tias lub hauv paus ntsiab lus ntawm kev hloov kho lub ntiaj teb tsis tshua muaj neeg yuav yog vim li hauv qab no:

(1) Sulfides thiab oxide suav nrog tsim los ntawm kev ntxiv cov khoom hauv ntiaj teb tsis tshua muaj rau cov hlau tuaj yeem dhau los ua cov khoom siv tsis sib xws ntawm cov hlau, uas tuaj yeem kho qhov sib xyaw ua ke sib xyaw ua ke thiab ua kom cov cheeb tsam hauv cov kab lus qis.

(2) Kev daws teeb meem ntawm cov khoom ntiaj teb tsis tshua muaj nyob hauv theem khoom yog qhov tsawg heev. Thaum cov hlau nchuav ua kom muaj zog, lub ntiaj teb tsis tshua muaj ntau ntxiv nyob rau theem ua kua nyob rau ntawm hauv ntej ntawm lub pob zeb loj tuaj, tiv thaiv cov kua muaju los ntawm kev loj hlob, yog li ua rau cov nplej zoo dua.

(3) Lub ntiaj teb tsis tshua muaj tshwm sim zoo ib yam nyob hauv thaj tsam ntawm cov qoob loo, txo qis kev sib cuam tshuam ntawm cov hlau, thiab txo qis kev quab yuam rau kev cog qoob loo, yog li cuam tshuam kev loj hlob ntawm austenite nplej. Raws li qhov tshwm sim, cov nplaim hluav taws martensite tsim los ntawm quenching kuj tseem me dua. .


Thov khaws qhov chaw thiab qhov chaw ntawm tsab xov xwm no kom luam tawm: Lub ntiaj teb tsis tshua muaj txiaj ntsig tuaj yeem txhim kho qhov tawv ntawm cov hlau cam khwb cia
