Behavior in Cast Iron
Heating white hypereutectic cast iron above 727 °C (1,341 °F) causes the formation of austenite in crystals of primary cementite. This austenisation of white iron occurs in primary cementite at the interphase boundary with ferrite. When the grains of austenite form in cementite, they occur as lamellar clusters oriented along the cementite crystal layer surface. Austenite is formed by withdrawal of carbon atoms from cementite into ferrite.

Famous quotes containing the words behavior, cast and/or iron:
“... two men could be just alike in all their dispositions to verbal behavior under all possible sensory stimulations, and yet the meanings or ideas expressed in their identically triggered and identically sounding utterances could diverge radically, for the two men, in a wide range of cases.”
—Willard Van Orman Quine (b. 1908)
“O eloquent, just, and mighty Death! whom none could advise, thou hast persuaded; what none hath dared, thou hast done; and whom all the world hath flattered, thou only hath cast out of the world and despised. Thou hast drawn together all the far-stretched greatness, all the pride, cruelty, and ambition of man, and covered it all over with these two narrow words, Hic jacet!”
—Sir Walter Raleigh (1552–1618)
“And thus we rust Life’s iron chain
Degraded and alone:
And some men curse, and some men weep,
And some men make no moan:
But God’s eternal Laws are kind
And break the heart of stone:”
—Oscar Wilde (1854–1900)
