Cov tswvyim yooj yim ntawm pearlite
Cov pearlite yog cov khoom siv sib xyaw ntawm ferrite thiab cementite, sawv cev los ntawm lub cim "P". Qhov nruab nrab ntawm cov pa roj carbon ntsiab lus ntawm cov qauv pearlite hauv carbon hlau yog li 0.77%. Nws cov yam ntxwv ua tau yog nruab nrab ntawm ferrite thiab cementite, uas yog, nws lub zog thiab hardness yog ho siab tshaj qhov ntawm ferrite. Plasticity thiab toughness yog phem tshaj li ntawm ferrite, tab sis zoo tshaj li cementite.
Pearlite yog cov qauv uas hauv austenite yog dej nag tib lub sijhawm li austenite, thiab cov qauv ntawm ferrite thiab cementite yog intercalated. Pearlite yog ib qho ntawm tsib yam qauv ntawm cov hlau-carbon alloy. Tus lej ntawd yog P. Nws yog npe tom qab tus neeg nrhiav khoom.
