    en.wikipedia.org/wiki/History_of_the_steel...

    Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.

    en.wikipedia.org/wiki/Ferrous_metallurgy

    Iron and steel artefacts, including high-carbon steel, were manufactured in northern Sweden, Finland and Norway (in the Cap of the North) from c. 200–50 BC. [ 59 ] [ 68 ] The production of ultrahigh carbon steel is attested at the Germanic site of Heeten in the Netherlands from the 2nd to 4th/5th centuries AD, in the Late Roman Iron Age .

    en.wikipedia.org/wiki/Science_fair

    A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.

  5. Steel - Wikipedia

    en.wikipedia.org/wiki/Steel

    Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Because of its high tensile strength and low cost, steel is one of the most commonly manufactured materials in the world.

  6. History of materials science - Wikipedia

    en.wikipedia.org/wiki/History_of_materials_science

    Materials science has shaped the development of civilizations since the dawn of humankind. Better materials for tools and weapons has allowed people to spread and conquer, and advancements in material processing like steel and aluminum production continue to impact society today.

  7. Steelmaking - Wikipedia

    en.wikipedia.org/wiki/Steelmaking

    Steel is made from iron and carbon. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and versatile. On its own, iron is not strong, but a low concentration of carbon – less than 1 percent, depending on the kind of steel – gives steel strength and other important properties.

  8. History of metallurgy in the Indian subcontinent - Wikipedia

    In this system, high-purity wrought iron, charcoal, and glass were mixed in crucibles and heated until the iron melted and absorbed the carbon. The resulting high-carbon steel, called fūlāḏ by the Arabs (Arabic: فولاذ, romanized: fūlāḏ, lit. 'steel; wootz') and wootz by later Europeans, was exported throughout much of Asia and Europe.

  9. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
