Why is metallurgy important

The production of component parts made from metals is traditionally divided into several major categories:. Techniques include chemical processing to convert minerals from inorganic compounds to useful metals and other materials. Concepts such as alloy design and microstructural engineering help link processing and thermodynamics to the structure and properties of metals.

Through these efforts, goods and services are produced. Metals and mineral products surround us everywhere — at home, on our way to and from work and in our offices or factories. They form the backbone of modern aircraft, automobiles, trains, ships, and endless recreational vehicles; buildings; implantable devices; cutlery and cookware; coins and jewelry; firearms; and musical instruments. The uses are endless. While threats abound from alternative material choices, metals continue to be at the forefront and are the only choice for many industrial applications.

We have the means to measure properties at the macro, micro, nano and atomic scales, giving us unprecedented access to fuel new developments. The strong dependence of our society on metals gives the profession of metallurgical engineering its sustained importance in the modern world. It is believed by most that our economic and technical progress into the 21st century will depend in large part on further advances in metal and mineral technology.

For example, advancements in energy technologies, such as the widespread use of nuclear fusion, will only be possible by material developments not yet in existence. The demand for careers in metallurgy is not at the forefront of our educational system due in large part to the inability of the metallurgical community to communicate to management our role in engineering and manufacturing.

While metallurgists should be involved in all aspects of modern engineering, this is seldom the case. The failure of management to understand what we do is often a failure to understand the engineering life cycle and the interrelationship of engineering disciplines to each other.

In the design of any engineered component, it is necessary to fully understand and address two key questions that the metallurgist is best qualified to answer, namely:.

What must the component endure during service i. Questions such as the following must be addressed: What are the rigors of the application, and what is the design life?

Must the component part provide premier service, or is there an adequate design life involved i. Com with specializations that help you build a successful career.

How Cloud with IoT is helping Healthcare sector? The science of metallurgy is subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction of metals, thermodynamics, electrochemistry, and chemical degradation corrosion. Topics studied in physical metallurgy include crystallography , material characterization, mechanical metallurgy, phase transformations, and failure mechanisms.

Historically, metallurgy has predominately focused on the production of metals. Metal production begins with the processing of ores to extract the metal, and includes the mixture of metals to make alloys. Metal alloys are often a blend of at least two different metallic elements. However, non-metallic elements are often added to alloys in order to achieve properties suitable for an application. The study of metal production is subdivided into ferrous metallurgy also known as black metallurgy and non-ferrous metallurgy also known as colored metallurgy.

Ferrous metallurgy involves processes and alloys based on iron while non-ferrous metallurgy involves processes and alloys based on other metals. The production of ferrous metals accounts for 95 percent of world metal production. Modern metallurgists work in both emerging and traditional areas as part of an interdisciplinary team alongside material scientists, and other engineers.

Some traditional areas include mineral processing, metal production , heat treatment, failure analysis, and the joining of metals including welding, brazing, and soldering.

Emerging areas for metallurgists include nanotechnology, superconductors, composites, biomedical materials, electronic materials semiconductors , and surface engineering.

After mining, large pieces of the ore feed are broken through crushing or grinding in order to obtain particles small enough where each particle is either mostly valuable or mostly waste. Concentrating the particles of value in a form supporting separation enables the desired metal to be removed from waste products. Mining may not be necessary, if the ore body and physical environment are conducive to leaching. Leaching dissolves minerals in an ore body and results in an enriched solution.
