ledeburite मीनिंग इन हिंदी

उदाहरण वाक्य

1. Ledeburite is very hard, making the cast-iron very brittle.
2. White cast-iron is composed mostly of a microstructure called ledeburite mixed with pearlite.
3. Ledeburite arises when the carbon content is between 2.06 % and 6.67 %.
4. Ledeburite-II ( at ambient temperature ) is composed of cementite-I with recrystallized secondary cementite ( which separates from austenite as the metal cools ) and ( with slow cooling ) of pearlite.
5. Two methods of tempering are used, called " white tempering " and " black tempering . " The purposes of both tempering methods is to cause the cementite within the ledeburite to decompose, increasing the ductility.
6. The pearlite results from the eutectoidal decay of the austenite that comes from the ledeburite-I at 723 �C . During more rapid cooling, bainite can develop instead of pearlite, and with very rapid cooling martensite can develop.
7. Since bainite ( shown as ledeburite on the diagram at the bottom of this page ) and pearlite each have ferrite as a component, any iron-carbon alloy will contain some amount of ferrite if it is allowed to reach equilibrium at room temperature.
