Ferrous metallurgy is the metallurgy of iron and alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from at least Greece to India, and more ...

Abstract Metallurgical and mechanical analyses were performed on steel and rivet samples recovered from the wreck of the RMS Titanic. It was found that the steel possessed a ductile-to-brittle transition temperature that was very high for this type of steel, making the material brittle at ice water temperatures.

The age of iron: from 1500 BC: The next great development in metallurgy involves a metal which is the most abundant in the earth's surface but which is much more difficult to work than copper or tin. It is iron, with a melting point too high for primitive furnaces to extract it in pure form from its ore.

White cast iron, or white iron, which is harder and more brittle, is made by cooling the molten iron rapidly. The carbon remains distributed throughout the iron as cementite (iron carbide, Fe 3 C). A malleable cast iron can be made by annealing white iron castings in a special furnace.

Metallurgy of iron. Iron is an important constituent of hemoglobin, which is in blood. Iron is the metal used most widely in industries and hence may be called the king of metals. It is the second most abundant metal after aluminum. Iron does not occur in native state, since it is oxidized easily.

Quick Introduction to Ancient Metallurgy. Despite this limitation, copper came to be more and more widely used, and archaeologists, especially those working in the Near East, sometimes speak of a Copper Age or "Chalcolithic" (kal-ko-LITH-ic) period from about 5000 to about 3000 BC in that region, or from the end of the Neolithic to the beginning of the Bronze Age.

Metallurgy, art and science of extracting metals from their ores and modifying the metals for use. Metallurgy customarily refers to commercial as opposed to laboratory methods. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.
