WORLD HISTORY

Detailed explanation-1: -The science of metallurgy is further 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.

Detailed explanation-2: -Metallurgy is the term for all of the science and technology used in relation to metal – for its extraction from ore, its refining, the creation of alloys, and its implementation in functional products. Metalworking is a discrete process – not part of metallurgy but entirely dependent on metallurgy.

Detailed explanation-3: -Metals are commercially extracted from minerals at low cost and minimum effort. These minerals are known as ores. A substance which is added to the charge in the furnace to remove the gangue (impurities) is known as flux. Metallurgy deals with the process of purification of metals and the formation of alloys.

Detailed explanation-4: -Metallurgy in production engineering Common engineering metals are aluminium, chromium, copper, iron, magnesium, nickel, titanium and zinc. These are most often used as alloys.
