Vim li cas thiaj yog scaffolding kuj sib nqus

Hom kev ua kom tsis muaj zog yog qhov sib nqus lossis sib nqus, sib nqus tsis muaj zog, thiab martensite lossis ferrite yog sib nqus.

Cov scaffold feem ntau siv los ua cov ntawv dai kom zoo nkauj feem ntau yog cov ntaub ntawv ntawm 304 cov ntaub ntawv tsis muaj zog lossis tsis muaj zog. Txawm li cas los xij, vim muaj tshuaj lom neeg sib xyaw ua ke lossis kev ua haujlwm sib txawv tshwm sim los ntawm smelting, condmentaries kuj tseem yuav tau pom tias yog vim li cas thiaj li tsis tsim nyog?

Vim kev tiv thaiv kev sib cais lossis kev kho kom sov sov thaum lub sijhawm smelting, ib qho me me ntawm martensite lossis ferrite qauv hauv Austenite 304 Scaffold yuav tshwm sim. Nyob rau hauv txoj kev no, yuav muaj yuav tsis muaj zog magnetism nyob rau hauv 304 Scaffolds.

Tsis tas li, tom qab 304 Scaffoldings yog cov khaub thuas txias, tus qauv yuav hloov pauv mus rau hauv martensite. Qhov ntau dua cov qib ntawm kev ua haujlwm txias ua haujlwm, cov martension ntau dua thiab ntau dua cov khoom sib nqus ntawm cov hlau. Zoo li ib pob ntawm cov hlau tsoo, φ76 hlab yog tsim tawm yam tsis muaj qhov pom tseeb ntawm, thiab φ9.5 hlab yog tsim tawm. Vim tias txoj hlua khi loj yog qhov loj dua, kev sib nqus ntawm lub raj, tshwj xeeb yog qhov sib txawv ntawm cov raj, tshwj xeeb yog khaus ntau dua thiab cov hlau nplaum yog qhov pom tseeb.

Txhawm rau tshem tawm cov khoom sib nqus ntawm 304 cov ntawv ntawm cov hlau tshwm sim los ntawm cov qauv Austenite, yog kev tshem tawm cov khoom sib nqus. Tshwj xeeb, lub magnetism ntawm 304 Scaffolds tshwm sim los ntawm cov laj thawj saum toj no yog tsis nyob rau lwm cov ntaub ntawv, xws li cov hlau sib txuas, uas txhais tau tias cov hlau ib txwm qhia tsis muaj zog hlau nplaum.

Qhov no qhia rau peb tias yog tias scaffold yog cov sib nqus tsis muaj zog lossis tsis sib nqus txhua, nws yuav tsum tau raug txiav txim li 304 lossis 316 cov khoom siv; Yog tias nws yog tib yam li cov roj carbon hlau, nws qhia tau muaj zog magnetism, vim tias nws raug txiav txim tsis yog 304 cov ntaub ntawv.
