Quench hardening
| Глоссарий в области цветной металлургии |
Hardening a ferrous alloy by austenitizing and then cooling rapidly enough so that some or all of the austenite transforms to martensite. the austenitizing temperature for hypo eutectoid steels is usually above ac3 and for hypereutectoid steels usually between acl and accm.

Упрочнение при закалке, русский
(1) упрочнение некоторых альфа-бета-сплавов (наиболее часто некоторых медных и титановых сплавов) термообработкой на твердый раствор или закалкой для получения структуры мартенситного типа. (2) в железных сплавах, упрочнение аустенитизацией, с последующим охлаждением с такой скоростью, что некоторое количество аустенита превращается в мартенсит.

Hardener, английский
- Отвердитель
- A substance or mixture of substances that is part of an adhesive and is used to promote curing by taking part in the reaction.
Hardener (rt), английский
An agent incorporated into the fixer solution to harden the emulsion during the fixing process. the acid hardener prevents the swelling of the emulsion and facilitates the drying process.
Hardening, английский
- Used to describe the resulting condition of a worker when his boss gives him to much work to do. the body just stiffens into a rigor mortis state and the worker becomes unable to function. from a dilbert cartoon by scott adams example b. isok, i have another project for you. (isok then stiffens like a board, arms spread wide.) b. isok, are you hardening?
- Усиление защиты
- Твердение; отверждение; упрочнение, повышение прочности; закалка о ~ in the presence of water твердение (бетона) при увлажнении
- Hardening is the process of identifying and fixing vulnerabilities on a system.
- The use of physical and firmware modifications that make the hardware more difficult to alter without damaging the hardware. these modifications can also prevent hacking that can disable the metering of a prepaid or subscription computer.
- Heating metal to within its critical range as in annealing, followed by rapid cooling as in quenching.
Hardening media, английский

Austenitizing, английский
Martensite, английский
- Acicular (needlelike) microstructure produced by fast cooling or quenching of metals and alloys such as steel.
- The hard steel with such microstructure produced by fast cooling of austenite. martensite is a constituent commonly found in quenched steel. martensite finish temperature: temperature at which martensite formation is completed as steel cools. martensite start temperature: temperature at which martensite starts to form as steel cools.
Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.
- Температура
- Температура тмр test methods and procedures методы проведения испытаний и последовательность их проведения тмр theodolite measuring point кинотеодолитная станция
- Temperatura, fiebre
- The condition attained when the wetted wick of a wet-bulb thermometer has reached a stable and constant temperature when exposed to moving air in excess of 900 ft (274.3 m) per minute.
- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).
- Повышение температуры бетона ~ of truss высота фермы jet ~ высота подъёма горизонтальной неизотермической приточной струи, «всплывающей» над приточным отверстием
- Температура ~ of adiabatic saturation температура адиабатического насыщения
- Normal adult temperature varies among horses, but will usually range in degrees from 99.5°f to 100.5°f.
- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
- Measure of the intensity of particle motion in degrees celsius (°c), degrees fahrenheit (°f) or, in the absolute scale, kelvin (k) or degrees rankine (°r). an increment of 1 k = 1 °c = 1.8 °r = 1.8 °f. compare heat.
