Lub zog Aspect
Tsawg Pearlite Proportion (High ferrite Proportion): Thaum qhov kev faib ua feem ntawm ferrite nyob rau hauv kub - dov steel daim hlau yog kuj siab thiab cov ntsiab lus pearlite yog tsawg, lub zog kuj tsawg. Piv txwv li, hauv qee qhov qis - carbon steels, cov ntsiab lus ferrite yuav siab li 90% thiab cov ntsiab lus pearlite kuj me me. Vim yog lub zog tsawg ntawm ferrite nws tus kheej, lub zog tensile ntawm hom steel phaj yuav nyob ib ncig ntawm 300 - 400MPa. Qhov no yog vim hais tias ferrite yog ib qho interstitial khoom tov ntawm carbon yaj nyob rau hauv - Fe, thiab nws cov qauv lattice yog ib txwm tsis tu ncua thiab tsis kam mus rau dislocation txav kuj me me. Thaum lub sij hawm stretching txheej txheem, cov khoom yog prone rau yas deformation, yog li lub zog ntawm steel phaj tsis siab.

 

Siab Pearlite Proportion (Low Ferrite Proportion): Raws li qhov kev faib ua feem ntawm pearlite nce, lub zog ntawm steel phaj yuav nce ntau. Pearlite yog cov khoom sib xyaw ua ke ntawm cov txheej txheem sib txawv ntawm ferrite thiab cementite. Cementite muaj siab hardness thiab brittleness, thiab alternately txheej txheem ntawm cementite thiab ferrite tuaj yeem cuam tshuam zoo rau kev txav mus los. Thaum cov ntsiab lus pearlite kuj siab, piv txwv li, hauv qee qhov nruab nrab - carbon steels, cov ntsiab lus pearlite tuaj yeem ncav cuag 50% - 60%, thiab nws lub zog tensile tuaj yeem nce mus txog ib ncig ntawm 500 - 600MPa. Qhov no yog vim hais tias thaum lub sij hawm stretching txheej txheem, dislocations yuav tsum tau kov yeej ntau kuj coj los ntawm pearlite qauv los deform cov khoom, yog li ua rau lub zog ntawm steel phaj.

 

Toughness Aspect
Tsawg Pearlite Proportion (High ferrite Proportion): Hlau daim hlau uas muaj feem ntau ntawm ferrite muaj zoo toughness. Ferrite muaj qhov zoo toughness thiab plasticity thiab tuaj yeem dhau mus rau qib loj ntawm cov yas deformation yam tsis muaj kev tawg thaum raug rau qee qhov kev quab yuam sab nraud. Qhov no ua rau cov phaj hlau nqus tau ntau lub zog thaum raug cov khoom thauj xws li cuam tshuam lossis khoov. Piv txwv li, hauv qee qhov kev thov uas yuav tsum tau ua kom muaj zog zoo, xws li cov kab hluav taws xob tiv thaiv kev sib tsoo ntawm lub tsheb, tsim nyog ua kom cov ferrite feem ntau tuaj yeem ua rau cov khoom siv tau zoo nqus lub zog thiab txo kev puas tsuaj thaum sib tsoo.

Siab Pearlite Proportion (Low Ferrite Proportion): Raws li kev faib ua feem ntawm pearlite nce, lub toughness yuav maj mam txo. Vim tias cementite nyob rau hauv pearlite muaj siab hardness thiab brittleness, thaum lub pearlite cov ntsiab lus kuj siab, cementite yuav ua rau tawg qhov chaw thaum cov hlau phaj raug rau sab nraud quab yuam, thiab cov kab nrib pleb yuav kis tau raws li kev sib tshuam ntawm cementite thiab ferrite, ua rau txo qhov toughness ntawm steel phaj. Txawm li cas los xij, yog tias muaj qee cov qauv ua kom zoo nkauj hauv pearlite matrix lossis tsim nyog ntxiv ntawm cov ntsiab lus hlau, qhov toughness kuj tuaj yeem txhim kho rau qee qhov.

 

Plasticity Aspect
Tsawg Pearlite Proportion (High Ferrite Proportion): Hlau daim hlau feem ntau yog tsim los ntawm ferrite muaj cov yas zoo. Vim tias ferrite nws tus kheej muaj cov yas zoo, nws qhov elongation tom qab tawg yog qhov siab ntawm qhov ntsuas tensile. Piv txwv li, hauv qee cov khoom siv hlau me me nrog cov ntsiab lus ferrite siab, qhov elongation tom qab tawg tuaj yeem ncav cuag li 30% - 40%. Qhov no txhais tau hais tias cov hlau phaj tuaj yeem ua rau muaj qhov deformation loj yam tsis muaj kev tawg thaum lub sij hawm ncab, thiab cov yas zoo no ua rau cov khoom siv yooj yim rau kev ua tiav thiab tsim, xws li stamping thiab dabtsi yog khoov cov txheej txheem.
