heat treatment definition

The physical properties like ductility, malleability, hardness can be altered with this heat treatment process. Formed when … 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. These mechanical properties could be hardness, strength or ductility. Contrast bath: This is a bath that involves alternating heat and cold. 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. Heat treatment process is the controlled heating or cooling of plain carbon steel or alloy steel. 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. Heat-treat definition, to subject (a metal or alloy) to controlled heating and cooling to improve hardness or other properties. Heat treatments are also used in the manufacture of many other materials, such as glass. The basic purpose of heat treatment process is to change the physical properties of the metal. It is very closely linked to the manufacture of steel products: about 80 percent of heat treated parts are made of steel. Heat treating aims to develop specific microstructures within a material. Austenite: A solid mixture of iron and carbon (can be other elements). The STANDS4 Network ... Rate this definition: Heat Treatment. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Login . The most common application is metallurgical. Information and translations of heat treatment in the most comprehensive dictionary definitions resource on the web. Effects of heat-treating. Heat treatment process is a technique in which metals in the solid state are subjected to heating and cooling processes. Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. What does HEAT TREATMENT mean? 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. Definition of HEAT TREATMENT in the Definitions.net dictionary. 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. Heat Treatment is the second album by rock and roll singer-songwriter Graham Parker and The Rumour. Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. Use caution when implementing a heat treatment or cold treatment. What is heat treatment? Meaning of HEAT TREATMENT. Alloy: A mixture of two or more chemical elements, at least one of which being metal, with metallic properties. Heat Treatments: Definition Heat treatments are applications of therapeutic thermal agents to specific body areas experiencing injury or dysfunction. Adjusting the carbon content is the simplest way to change the mechanical properties of steel. Information and translations of HEAT TREATMENT in the most comprehensive dictionary definitions resource on the web. 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. Heat treatment of steel is used to change its structure in order to obtain certain mechanical properties. See more.
