Properties, Composition, and Production of Metal Alloys
Individual pure metals may possess useful properties such as good electrical conductivity, high strength, and hardness, or heat and corrosionresistance. Commercial metal alloys attempt to combine these beneficial properties in order to create metals more useful for particular applications than any of their component elements. Steel, for example, requires the right combination of carbon and iron (about 99% iron and 1% carSee more on thoughtco alloy definition properties examples facts britannica Heat treatmentMetallurgy - Physical metallurgy | BritannicaThe yield stress of a metal is determined by the resistance to slipping of one plane of atoms over another. Various barriers to slip can be produced by heat treatment and alloying; examples of such barriers are grain boundaries, fine precipitates, distortion introduced by cold working the metal, and alloying elements dissolved in the metal.Metallurgy - Alloying | BritannicaFor example, adding lead to tin lowers the melting point of the tin-rich alloy, and adding tin to lead lowers the melting point of the lead-rich alloy. A 62-percent-tin 38-percent-lead alloy, which is called the eutectic composition, has the lowest melting point of all, much lower than that of either metal.

Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc.Heat Treatment of Metals: History and Objectives | MetallurgyMuch of the versatility of steel arises due to the fact that the properties of the steel can be controlled and changed at will (though within reasonable good limits) by heat treatment. For example, if the steel is to be deformed into intricate shape, then, it can be made very soft and ductile by one heat treatment cycle; if on the other hand, it is supposed to resist wear, it can be heat treated to a very hard and wear

Duralumin - Chemical Composition, Mechanical Properties alloy definition properties examples facts britannica Heat treatment
Duralumin is a strong, lightweight alloy of aluminium discovered in 1910 by Alfred Wilm, a German metallurgist. It is relatively soft, ductile and easily workable under normal temperature. The alloy can be rolled, forged and extruded into various forms and products. The tensile strength of duralumin is higher than aluminum, although its resistance to corrosion is poor. The electrical and heat conductivity of duralumin is less than that of pure aluminum and more than that of steel. It was initially used in rigid airSee more on azom alloy definition properties examples facts britannica Heat treatmentCopper Alloys - an overview | ScienceDirect TopicsIn the main, metallic objects were fabricated from a wide variety of alloys of gold, silver, copper, arsenic, tin, antimony and zinc.
