cementite தமிழ் அர்த்தத்தின் உதாரணம்:

கடின இரும்பு நானோகம்பிகளும் கரிம நானோகுழாய்களும் உவூட்சு எஃகின் நுண்கட்டமைப்பில் (மைக்ரோஸ்ட்ரக்ச்சர்) இடம்பெறுவதை, TU டிரெஸ்டனைச் சேர்ந்த பீட்டர் பாஃப்லர் கண்டுபிடித்துள்ளார்.

இதனால் கடின இரும்பு உருவாகிறது.

cementite's Usage Examples:

The fact that this decrease of strength begins shortly after the carboncontent rises above the eutectoid or pearlite ratio of o 90% is natural, because the brittleness of the cementite which, in hypereutectoid steels, forms a more or less continuous skeleton (Alloys, Pl.

Thus, sudden cooling from a red heat leaves the carbon not in definite combination as cementite, but actually dissolved in (3and 7-allotropic iron, in the conditions known as martensite and austenite, not granitic but glass-like bodies, of which the " hardened " and " tempered " steel of our cutting tools in large part consists.

Though carbon passes far more readily under most conditions into the state of cementite than into that of graphite, yet of the two graphite is the more stable and cementite the less stable, or the ' metastable " form.

Steel differs in many ways from iron in respect of atmospheric corrosion; the heterogeneous nature of steel gives occasion to a selective rusting, ferrite is much more readily attacked than the cementite and pearlite; moreover, the introduction of other elements may retard rusting; this is particularly the case with the nickel-steels.

would have consisted chiefly of graphite with pearlite and ferrite (which are all relatively soft bodies), if thus chilled and annealed consists of cementite and pearlite.

On cooling into region 6 or 8 austenite should normally split up into ferrite and cementite, after passing through the successive stages of martensite, troostite and sorbite, Fe 0 C Fe 3 C +Fe(i 3).

75% for rails, implying the presence of o 75% of cementite in the first two, 3% in the third and 7.

0 The constitution and properties of such a series of cast irons, all containing 4% of carbon but with that carbon shifting pro o v,,3 950 R portion of ferrite and cementite respectively in the matrix, DEF, KS and TU reproduced from fig.

Beta (13) iron, an unmagnetic, intensely hard and brittle allotropic form of iron, though normal and stable only in the little triangle GHM, is yet a state through which the metal seems always to pass when the austenite of region 4 changes into the ferrite and cementite of regions 6 and 8.
