Heat treating adds about $15 billion per year in value to metal products by imparting specific properties that are required if parts are to function successfully. See more. Heat treatment process is the controlled heating or cooling of plain carbon steel or alloy steel. Adjusting the carbon content is the simplest way to change the mechanical properties of steel. Login . Heat Treatments: Definition Heat treatments are applications of therapeutic thermal agents to specific body areas experiencing injury or dysfunction. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treating aims to develop specific microstructures within a material. Additional changes are made possible by heat-treating—for instance, by accelerating the rate of cooling through the austenite-to-ferrite transformation point, shown by the P-S-K line in the figure. Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The physical properties like ductility, malleability, hardness can be altered with this heat treatment process. Meaning of HEAT TREATMENT. The basic purpose of heat treatment process is to change the physical properties of the metal. What does HEAT TREATMENT mean? What is heat treatment? Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. CHAPTER 2 BASIC HEAT TREATMENT As Steelworkers, we are interested in the heat treat-ment of metals, because we have to know what effects the heat produced by welding or cutting has on metal. Formed when … These mechanical properties could be hardness, strength or ductility. Effects of heat-treating. Heat treatments are … Heat Treating Overview Heat treating, as the name implies, is a series of treatments in which heat is used to alter the properties of a metal or alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Heat treatment of steel is used to change its structure in order to obtain certain mechanical properties. Heat-treat definition, to subject (a metal or alloy) to controlled heating and cooling to improve hardness or other properties. Contrast bath: This is a bath that involves alternating heat and cold. Heat Treatment is the second album by rock and roll singer-songwriter Graham Parker and The Rumour. Information and translations of heat treatment in the most comprehensive dictionary definitions resource on the web. Definition of HEAT TREATMENT in the Definitions.net dictionary. The most common application is metallurgical. Austenite: A solid mixture of iron and carbon (can be other elements). Alloy: A mixture of two or more chemical elements, at least one of which being metal, with metallic properties. Use caution when implementing a heat treatment or cold treatment. Heat treatment process is a technique in which metals in the solid state are subjected to heating and cooling processes. Paraffin wax or warm wax: This can be used to apply heat via machines that are highly regulated and use a wax mixture that avoids skin burns. It is very closely linked to the manufacture of steel products: about 80 percent of heat treated parts are made of steel.
