This was produced using the crucible steel method, based on the earlier Indian wootz steel. This process was adopted in the Middle East using locally produced steels. The exact process remains unknown, but it allowed carbides to precipitate out as micro particles arranged in sheets or bands within the body of a blade. Carbides are far harder ...
Steelmaking is the process of producing steel from iron ore and/or scrap. Steel has been made for millennia, and was commercialized on a massive scale in the 1850s and 1860s, using the Bessemer and Siemens-Martin processes. Two major commercial processes are used.
Huntsman's process was the first to produce a fully homogeneous steel. Unlike previous methods of steel production, the Huntsman process was the first to fully melt the steel, allowing the full diffusion of carbon throughout the liquid. With the use of fluxes it also allowed the removal of most impurities, producing the first steel of modern ...
Iron, steel, and ferrous metals constitute a large portion of collections in museums. The conservation and restoration of iron and steel objects is an activity dedicated to the preservation and protection of objects of historical and personal value made from iron or steel. When applied to cultural heritage this activity is generally undertaken ...
The first crucible steel was the wootz steel that originated in India before the beginning of the common era. [55] Wootz steel was widely exported and traded throughout ancient Europe, China, the Arab world, and became particularly famous in the Middle East, where it became known as Damascus steel. Archaeological evidence suggests that this ...
The origin of the name "Damascus Steel" is contentious. Islamic scholars al-Kindi (full name Abu Ya'qub ibn Ishaq al-Kindi, circa 800 CE – 873 CE) and al-Biruni (full name Abu al-Rayhan Muhammad ibn Ahmad al-Biruni, circa 973 CE – 1048 CE) both wrote about swords and steel made for swords, based on their surface appearance, geographical location of production or forging, or the name of the ...
The tatara (鑪) is a traditional Japanese furnace used for smelting iron and steel. The word later also came to mean the entire building housing the furnace. The traditional steel in Japan comes from ironsand processed in a special way, called the tatara system. [1] Iron ore was used in the first steel manufacturing in Japan.
Iron is the outlier at 1538 °C (2800 °F), [21] making it far more difficult to melt in antiquity. Cultures developed ironworking proficiency at different rates; however, evidence from the Near East suggests that smelting was possible but impractical circa 1500 BC, and relatively commonplace across most of Eurasia by 500 BC.
