Damascus steel is the forged steel of the blades of swords smithed in the Near East from ingots of carbon steel imported from Southern India or made in production centers in Sri Lanka or Khorasan, Iran. These swords are characterized by distinctive patterns of banding and mottling reminiscent of flowing water, sometimes in a "ladder" or "rose" pattern. Such blades were reputed to be tough, resistant to shattering, and capable of being honed to a sharp, resilient edge.
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys.
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. Steel is used in buildings, as concrete reinforcing rods, in bridges, infrastructure, tools, ships, trains, cars, bicycles, machines, electrical appliances, furniture, and weapons.
Noricum is the Latin name for the kingdom or federation of tribes that included most of modern Austria and part of Slovenia. In the first century AD, it became a province of the Roman Empire. Its borders were the Danube to the north, Raetia and Vindelici to the west, Pannonia to the east and south-east, and Italia to the south. The kingdom was founded around 400 BC, and had its capital at the royal residence at Virunum on the Magdalensberg.
Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe3C. By weight, it is 6.67% carbon and 93.3% iron. It has an orthorhombic crystal structure. It is a hard, brittle material, normally classified as a ceramic in its pure form, and is a frequently found and important constituent in ferrous metallurgy. While cementite is present in most steels and cast irons, it is produced as a raw material in the iron carbide process, which belongs to the family of alternative ironmaking technologies. The name cementite originated from the theory of Floris Osmond and J. Werth, in which the structure of solidified steel consists of a kind of cellular tissue, with ferrite as the nucleus and Fe3C the envelope of the cells. The carbide therefore cemented the iron.
The Hallstatt culture was the predominant Western and Central European archaeological culture of the Late Bronze Age from the 12th to 8th centuries BC and Early Iron Age Europe from the 8th to 6th centuries BC, developing out of the Urnfield culture of the 12th century BC and followed in much of its area by the La Tène culture. It is commonly associated with Proto-Celtic speaking populations.
In materials science, quenching is the rapid cooling of a workpiece in water, gas, oil, polymer, air, or other fluids to obtain certain material properties. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favorable and kinetically accessible; for instance, quenching can reduce the crystal grain size of both metallic and plastic materials, increasing their hardness.
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries.
Sword making, historically, has been the work of specialized smiths or metalworkers called bladesmiths or swordsmiths. Swords have been made of different materials over the centuries, with a variety of tools and techniques. While there are many criteria for evaluating a sword, generally the four key criteria are hardness, strength, flexibility and balance. Early swords were made of copper, which bends easily. Bronze swords were stronger; by varying the amount of tin in the alloy, a smith could make various parts of the sword harder or tougher to suit the demands of combat service. The Roman gladius was an early example of swords forged from blooms of steel.
Voestalpine AG – stylized as voestalpine – is an Austrian steel-based technology and capital goods group based in Linz, Austria. The company is active in steel, automotive, railway systems, profilform and tool steel industries. As of 2017, it is one of the few profitable steel companies in Europe.
Noreia is an ancient lost city in the Eastern Alps, most likely in southern Austria. While according to Julius Caesar it is known to have been the capital of the Celtic kingdom of Noricum, it was already referred to as a lost city by Pliny the Elder. The location of Noreia has not been verified by modern researchers.
Japanese swordsmithing is the labour-intensive bladesmithing process developed in Japan beginning in the sixth century for forging traditionally made bladed weapons (nihonto) including katana, wakizashi, tantō, yari, naginata, nagamaki, tachi, nodachi, ōdachi, kodachi, and ya (arrow).
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric 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 in the region from Greece to India, The use of wrought iron was known by the 1st millennium BC, and its spread defined the Iron Age. During the medieval period, smiths in Europe found a way of producing wrought iron from cast iron, in this context known as pig iron, using finery forges. All these processes required charcoal as fuel.
Swords made of iron appear from the Early Iron Age, but do not become widespread before the 8th century BC.
The Alpine regiments of the Roman army were those auxiliary units of the army that were originally raised in the Alpine provinces of the Roman Empire: Tres Alpes, Raetia and Noricum. All these regions were inhabited by predominantly Rhaetian peoples and Celtic-speaking tribes. They were annexed, or at least occupied, by the emperor Augustus' forces during the period 25–14 BC. The term "Alpine" is used geographically in this context and does not necessarily imply that the regiments in question were specialised in mountain warfare. However, in the Julio-Claudian period, when the regiments were still largely composed of Alpine recruits, it is likely that they were especially adept at mountain operations.
Metals and metal working had been known to the people of modern Italy since the Bronze Age. By 53 BC, Rome had expanded to control an immense expanse of the Mediterranean. This included Italy and its islands, Spain, Macedonia, Africa, Asia Minor, Syria and Greece; by the end of the Emperor Trajan's reign, the Roman Empire had grown further to encompass parts of Britain, Egypt, all of modern Germany west of the Rhine, Dacia, Noricum, Judea, Armenia, Illyria, and Thrace. As the empire grew, so did its need for metals.
The Roman army of the mid-Republic, also called the manipular Roman army or the Polybian army, refers to the armed forces deployed by the mid-Roman Republic, from the end of the Samnite Wars to the end of the Social War. The first phase of this army, in its manipular structure, is described in detail in the Histories of the ancient Greek historian Polybius, writing before 146 BC.
The Erzberg mine is a large open-pit mine located in Eisenerz, Styria, in the central-western part of Austria, 60 km north-west of Graz and 260 km south-west of the capital, Vienna. The deposit lies at the Northern fringes of the Eastern greywacke zone, a band of Paleozoic metamorphosed sedimentary rocks that run east-west through the Austrian Alps, rich in copper and iron ore. Erzberg is the largest iron ore reserves in Austria, having estimated reserves of 235 million tonnes of ore. The mine produces around 3.2 million tonnes of pure iron ore per year. It is also the site of the annual Erzberg Rodeo hard enduro motorbike race.
The Erzberg Rodeo is an Austrian motorcycle enduro event started in 1995 and held annually in May or June, run on ore. It is the largest of its kind in Europe.
The different types of bladed weapons have been of great importance throughout history. In addition to its use for fighting, or in wars, the bladed weapons have been the object of special considerations forming part of funerary rituals, mythology and other ancestral traditions.
