Marine Qib Ah36 Hlau Phaj Rau Nkoj Lub Tsev

Qhov cuam tshuam ntawm Carbon Cov ntsiab lus ntawm lub Toughness ntawm Ah36 High-Strength Nkoj Phaj Hlau

Ah36 high-strength nkoj phaj hlau yog dav siv nyob rau hauv kev lag luam shipbuilding vim nws cov khoom siv zoo heev. Ib qho ntawm cov khoom tseem ceeb yog toughness, uas txiav txim siab lub peev xwm ntawm cov hlau los tiv thaiv kev cuam tshuam thiab tam sim ntawd loads yam tsis muaj fracturing. Cov ntsiab lus carbon nyob rau hauv Ah36 steel plays lub luag haujlwm tseem ceeb hauv kev cuam tshuam nws lub zog. Hauv tsab xov xwm no, peb yuav tshawb txog kev sib raug zoo ntawm cov ntsiab lus carbon thiab toughness ntawm Ah36 steel, txhawb nqa los ntawm cov ntaub ntawv thiab kev tshuaj xyuas.


Kev sim cov ntaub ntawv ntawm qhov cuam tshuam ntawm cov ntsiab lus carbon ntawm Toughness

Txhawm rau nkag siab txog qhov cuam tshuam tshwj xeeb ntawm cov ntsiab lus carbon ntawm lub zog ntawm Ah36 steel, ntau qhov kev sim tau ua. Cov txiaj ntsig tau qhia meej meej ntawm cov ntsiab lus carbon thiab toughness.

1. Cov ntsiab lus carbon tsawg (<0.15%)

- Ntawm cov ntsiab lus tsis tshua muaj carbon, Ah36 steel nthuav tawm siab toughness. Cov hlau yog cov ductile thiab tuaj yeem nqus tau ntau lub zog ua ntej tawg. Piv txwv li, hauv ib qho kev sim, ib qho piv txwv nrog cov ntsiab lus carbon ntawm 0.12% muaj Charpy V-notch cuam tshuam lub zog ntawm 200 J ntawm chav tsev kub.
- Cov ntsiab lus ntawm cov pa roj carbon tsawg tso cai rau cov qauv nplej zoo dua, uas txhim kho cov ductility thiab toughness ntawm cov hlau. Tsis tas li ntawd, muaj lwm cov ntsiab lus alloying thiab kev kho cua sov kom zoo tuaj yeem txhim kho qhov toughness ntawm cov pa roj carbon tsawg.
2. Cov ntsiab lus Carbon nruab nrab (0.15% - 0.20%)

- Raws li cov ntsiab lus carbon nce mus rau qhov nruab nrab, lub zog ntawm Ah36 steel pib poob qis. Cov hlau ua tsis tshua muaj ductile thiab feem ntau ua rau tawg tawg. Piv txwv li, ib qho piv txwv nrog cov ntsiab lus carbon ntawm 0.18% tej zaum yuav muaj Charpy V-notch cuam tshuam lub zog ntawm 150 J ntawm chav tsev kub.
- Cov ntsiab lus nruab nrab ntawm cov pa roj carbon monoxide ua rau cov qauv coarser grain thiab tsim cov theem nkig ntau dua, uas txo cov toughness. Txawm li cas los xij, nrog kev kho kom zoo thiab kev kho cua sov, nws muaj peev xwm tswj tau qee theem ntawm toughness hauv cov pa roj carbon ntau.
3. High Carbon Content (>0.20%)

- Ntawm cov ntsiab lus carbon siab, lub zog ntawm Ah36 steel yog txo qis. Cov hlau ua tsis tshua muaj nkig thiab muaj peev xwm nqus tau lub zog ua ntej tawg. Piv txwv li, ib qho piv txwv nrog cov ntsiab lus carbon ntawm 0.25% tej zaum yuav muaj Charpy V-notch cuam tshuam lub zog ntawm tsuas yog 50 J ntawm chav tsev kub.
- Cov ntsiab lus ntawm cov pa roj carbon ntau ua rau muaj qhov nyuaj thiab nkig microstructure, nrog rau ntau cov cementite thiab lwm yam nkig. Qhov no ua rau cov hlau muaj kev cuam tshuam rau cov pob txha tawg thiab txo nws txoj kev tsim nyog rau cov ntawv thov uas yog qhov tseem ceeb heev.

Cov yam ntxwv cuam tshuam rau kev sib raug zoo ntawm cov ntsiab lus Carbon thiab Toughness

Ob peb yam tuaj yeem cuam tshuam kev sib raug zoo ntawm cov ntsiab lus carbon thiab toughness hauv Ah36 steel.

1. Alloying Elements

- Qhov sib ntxiv ntawm cov ntsiab lus alloying xws li manganese, silicon, thiab npib tsib xee tuaj yeem hloov kho qhov cuam tshuam ntawm cov pa roj carbon monoxide rau toughness. Cov ntsiab lus no tuaj yeem txhim kho lub zog thiab tawv tawv ntawm cov hlau los ntawm kev ua kom zoo dua cov qauv ntawm cov nplej, txhawb kev tsim cov theem muaj txiaj ntsig, thiab txhim kho hardenability.
- Piv txwv li, qhov sib ntxiv ntawm manganese tuaj yeem ua rau kom muaj zog ntawm Ah36 steel ntawm cov pa roj carbon ntau dua los ntawm kev txo qis kev tsim cov theem nkig thiab txhawb nqa cov pob txha tawg.
2. Kev kho cua sov

- Kev kho cua sov kom zoo kuj tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo dua qhov tawv ntawm Ah36 steel ntawm cov ntsiab lus sib txawv. Annealing, normalizing, thiab quenching thiab tempering yuav siv tau los tswj cov microstructure thiab mechanical zog ntawm cov hlau.
- Piv txwv li, quenching thiab tempering tuaj yeem ua rau muaj zog ntawm high-carbon Ah36 steel los ntawm kev txo cov brittleness thiab refining microstructure.
3. Microstructure

- Lub microstructure ntawm Ah36 steel, uas yog cuam tshuam los ntawm cov ntsiab lus carbon thiab kev kho cua sov, muaj kev cuam tshuam loj rau kev ua kom tawv. Fine-grained microstructures nrog kev sib npaug ntawm cov theem feem ntau yog ntau dua thiab tawv dua li ntxhib-grained lossis brittle microstructures.
- Piv txwv li, microstructure nrog cov sib xyaw ntawm ferrite thiab pearlite tuaj yeem muab cov tawv tawv zoo dua li cov txheej txheem microstructure los ntawm nkig theem xws li martensite lossis cementite.
