Ferrite - Pearlite Phase Composition
Ferrite: Ferrite yog ib qho khoom sib txuam ntawm cov pa roj carbon yaj hauv - Fe. Nws muaj zoo toughness thiab plasticity, tab sis kuj tsis tshua muaj zog. Nyob rau hauv kub - dov steel phaj dominated los ntawm ferrite, lub tensile lub zog feem ntau yog tsawg thiab. Txawm li cas los xij, lub xub ntiag ntawm ferrite tuaj yeem muab qee qhov kev sib tw ntawm cov hlau phaj, ua kom nws mus rau qee yam ntawm cov yas deformation yam tsis tau tawg thaum raug lub zog tensile.

 

Pearlite: Pearlite yog cov khoom sib xyaw ua ke ntawm cov txheej txheem ferrite thiab cementite. Cementite muaj siab hardness thiab brittleness. Kev sib hloov ntawm cov cementite thiab ferrite tuaj yeem cuam tshuam kev txav mus los thaum lub sijhawm ncab. Raws li cov ntsiab lus pearlite nce, lub zog tensile ntawm kub - dov steel phaj maj mam nce. Piv txwv li, nyob rau hauv qis - carbon steel, thaum pearlite cov ntsiab lus nce los ntawm ib tug tsawg theem, lub phaj lub peev xwm los tiv thaiv tensile deformation yog ho txhim khu kev qha.

 

Cov nyhuv ntawm Martensite Phase
Martensite yog ib qho supersaturated solid tov ntawm carbon nyob rau hauv - Fe. Nws tsim feem ntau yog vim qhov txias txias (quenching) ntawm cov hlau nyob rau hauv lub siab kub austenitic xeev. Martensite muaj zog heev thiab hardness. Thaum lub sij hawm martensite tam sim no nyob rau hauv ib tug kub-kuav los tiag steel phaj, nws tensile zog yuav ho nce. Qhov no yog vim hais tias cov pa roj carbon atoms nyob rau hauv martensite yog supersaturated thiab yaj nyob rau hauv lub lattice, ua rau ib tug loj lattice distortion thiab muaj zog hindrance rau dislocation txav. Txawm li cas los xij, martensite muaj qhov tsis zoo toughness. Yog li ntawd, txawm hais tias cov hlau phaj nrog ntau theem martensite muaj lub zog tensile siab, lawv yuav nkig thiab ua rau tawg tawg.

Cov nyhuv ntawm Phase Transformation thiab Composite Phase
Thaum lub sij hawm zus tau tej cov kub-kuav los tiag steel daim hlau, theem transformations ntawm txawv theem yuav ua tau tiav los ntawm kev tswj tej yam xws li cua txias npaum li cas thiab alloy muaj pes tsawg leeg. Piv txwv li, los ntawm kev kho cov cua txias kom zoo, austenite tuaj yeem hloov mus rau hauv bainite lossis martensite. Ntxiv mus, tiag tiag kub - dov steel daim hlau tej zaum yuav ib tug sib xyaw ntawm ntau theem, xws li ferrite - pearlite - bainite composite theem los yog ferrite - martensite composite theem. Cov qauv sib xyaw ua ke no tuaj yeem ua ke qhov zoo ntawm cov theem sib txawv. Los ntawm kev hloov pauv ntawm cov theem tsim nyog, lub zog tensile siab tuaj yeem ua kom ntseeg tau, thiab tib lub sijhawm, lub zog thiab lwm yam khoom siv ntawm cov hlau phaj tuaj yeem txhim kho. Piv txwv li, nyob rau hauv ib co high-kev kawm kub-kuav los tiag steel daim hlau, los ntawm cov txheej txheem tswj, ib tug tsim nyog tus nqi ntawm ferrite, pearlite thiab qis bainite muaj, yog li ua tau zoo tshuav nyiaj li cas ntawm tensile zog, toughness thiab plasticity.
