Argon oxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminum.After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization, reduction, and desulfurization. Hardness Argon oxygen decarburization Introduction The precipitation of a second phase is widely used to enhance the properties of metallic alloys (strength, tough-ness, creep resistance, etc.). Heat treating The An alloy is a mixture of chemical elements of which at least one is a metal.Unlike chemical compounds with metallic bases, an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity, ductility, opacity, and luster, but may have properties that differ from those of the pure metals, such as increased strength or hardness. Hardening is a metallurgical metalworking process used to increase the hardness of a metal. Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.The most common application is metallurgical.Heat treatments are also used in the manufacture of many other materials, such as glass.Heat treatment involves the use of heating or chilling, normally to Tool steel TR_redirect Defense Technical Information Center - DTIC View PDF; Download Full Issue; Materials Science and Engineering: A.
