   ledeburite
   The eutectic of the iron-carbon system, the constituents of which are austenite and cementite. The austenite decomposes into ferrite and cementite on cooling below the temperature at which transformation of austenite to ferrite or ferrite plus cementite is completed.

   Ledeburite
   In iron and steel metallurgy, `Ledeburite` is the eutectic that results when some forms of molten steel solidify. It is named after the metallurgist Karl Heinrich Adolf Ledebur (1837-1916). He was the first professor of metallurgy at the Bergakademie Freiberg. He discovered ledeburite in 1882. Ledeburite arises when the carbon content is between 2.06% and 6.67%. The eutectic mixture is 4.3% carbon. Its melting point is 1147ðC. At 4.3% carbon th...
