Description

A branch of materials science and engineering called metallurgy examines the physical and chemical properties of metallic elements, their intermetallic compounds, and the mixes of these elements that are referred to as alloys. The science and technology of metals, or how science is applied to the manufacturing of metals, as well as the engineering of metal components utilised in products for both customers and manufacturers, are all included in the field of metallurgy. The art of metalworking is distinct from metallurgy. Similar to how medicine depends on medical science for technical advancement, metalworking depends on metallurgy. A metallurgist is an expert in the practise of metalworking.

Chemical metallurgy and physical metallurgy are two further divisions of the science of metallurgy. The reduction, oxidation, and chemical behavior of metals are the main topics of study in chemical metallurgy. Mineral processing, metal extraction, thermodynamics, electrochemistry, and chemical deterioration (corrosion) are among the topics covered in chemical metallurgy. Physical metallurgy, on the other hand, is concerned with the mechanical, physical, and performance characteristics of metals. Crystallography, material characterization, mechanical metallurgy, phase transitions, and failure mechanisms are among the subjects covered in physical metallurgy.

Metal production has always been the main emphasis of metallurgy. The process of extracting metal from ores is the first step in the manufacture of metal, which also involves mixing different metals to create alloys. A minimum of two separate metallic components are frequently combined to form metal alloys. However, non-metallic components are frequently added to alloys to give them the desired qualities. Ferrous metallurgy, often known as "black metallurgy," and non-ferrous metallurgy, commonly known as "coloured metallurgy," are two subfields in the study of the production of metals. In contrast to non-ferrous metallurgy, which uses processes and alloys based on other metals, ferrous metallurgy uses processes and alloys based on iron. 95 percent of all metals produced worldwide are ferrous metals.

Modern metallurgists collaborate with material scientists, engineers, and other professionals in both new and established fields. Mineral processing, metal production, heat treatment, failure analysis, and metal joining (including welding, brazing, and soldering) are a few traditional fields. Nanotechnology, superconductors, composites, biological materials, electronic materials (semiconductors), and surface engineering are emerging fields for metallurgists. The development of the blast furnace, cast iron, hydraulic-powered trip hammers, and double acting piston bellows are only a few of the numerous applications, procedures, and equipment related to or involved in metallurgy that were established in ancient China.

In the process of extractive metallurgy, precious metals are removed from an ore and refined into a purer form. A metal oxide or sulphide must be reduced physically, chemically, or electrolytically to provide a purer metal. Three main streams are of importance to extractive metallurgists: feed, concentrate (metal oxide/sulphide), and tailings (trash).

After mining, big ore feed pieces are broken into smaller, more manageable pieces through crushing or grinding, where each particle is either mostly profitable or primarily trash depending on the mining method. It is possible to separate the required metal from waste products by concentrating the valuable particles into a form that supports separation.

Understanding the iron-carbon alloy system, which includes steels and cast irons, has received a lot of attention. In applications requiring great strength and cheap cost, plain carbon steels (those that essentially solely include carbon as an alloying element) are employed because they are resistant to corrosion and weight. Another component of the iron-carbon system is cast iron, which includes ductile iron. A non-magnetic application like directional drilling makes use of iron-manganese-chromium alloys.

The manufacturing of metallic components for use in consumer or engineering products is the focus of metallurgy in production engineering. Alloy manufacture, product shape, heat treatment, and surface treatment are included in this. Achieving balance between material qualities including cost, weight, strength, toughness, hardness, corrosion resistance, fatigue resistance, and performance in temperature extremes is the job of a metallurgist. The operating environment must be carefully taken into account in order to accomplish this purpose.
