hardening

تعريف hardening في الإنجليزية الإنجليزية القاموس.: An increase in resistance to indentation; Increasing the hardness of metal by suitable treatment, usually involving heating and cooling; (1) Describes a price which is gradually stabilizing; (2) a term indicating a slowly advancing market; The process of gradually acclimatizing greenhouse or indoor grown plants to outdoor growing conditions; Increasing hardness by suitable treatment, usually involving heating and cooling When applicable, the following more specific terms should be used: age hardening and precipitation hardening; The process of strengthening the shell and adductor muscle of oysters to improve shell-life [B C Shellfish industry]; a The heating and quenching of certain iron-base alloys from a temperature above the critical temperature range for the purpose of producing a hardness superior to that obtained when the alloy is not quenched This term is usually restricted to the formation of martensite; Making hard or harder; That which hardens, as a material used for converting the surface of iron into steel; the act of making something harder (firmer or tighter or more compact); present participle of harden; the process of becoming hard or solid by cooling or drying or crystallization; "the hardening of concrete"; "he tested the set of the glue"; abnormal hardening or thickening of tissue; heating and rapidly cooling steel; the act of making something harder (firmer or tighter or more compact) the process of becoming hard or solid by cooling or drying or crystallization; "the hardening of concrete"; "he tested the set of the glue"; {i} process of becoming stiff or hard; toughening; WHAT Process that increases the hardness of steel, i e , the degree to which steel will resist cutting, abrasion, penetration, bending, and stretching; In metallurgy, an increase in hardness of a metal induced, deliberately or accidentally, by hammering, rolling, drawing (see wire drawing), or other physical processes. The first few deformations imposed by such treatment weaken the metal, but because of the crystalline structure of metal its strength increases with continued deformations. Crystals slip against each other; but, because of the complexity of the crystal structure, the more such slips are multiplied, the more they tend to place obstacles in the way of further slippage, as the various dislocation lines crisscross each other.

case hardening: The process of imparting greater hardness to the surface of a piece of metal
case-hardening: Alternative spelling of case hardening
harden: To become hard
harden: To become or make a person or thing resistant or less sensitive
When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go. — KJV, Exodus 4:21.
harden: To make something hard(er)
radiation hardening: the protection of semiconductor devices from the effects of ionizing radiation
work hardening: The repeated plastic deformation of a material, causing a permanent distortion of its crystal structure, and an increase in its strength
Precipitation Hardening: Precipitation hardening, also called age hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some stainless steels
age hardening: Precipitation hardening, also called age hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some stainless steels
harden: {v} to make or grow hard, to confirm
case hardening: Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question has been formed into its final shape, but can also be done to increase the hardening element content of bars to be used in a pattern welding or similar process
precipitation hardening: (Metal İşleme) Precipitation hardening, also called age hardening or dispersion hardening, is a heat treatment technique used to strengthen malleable materials, especially non-ferrous alloys including most structural alloys of aluminium and titanium
strain hardening: (Mühendislik) Strain hardening, or work hardening, is an increase in the strength of a material due to plastic deformation. In metallic solids permanent change of shape is usually carried out on a microscopic scale by defects called dislocations which are created by stress and rearrange the material by moving through it. At normal temperatures these defects do not anneal out of the material but build up as the material is worked, interfering with one another's motion and thus increasing strength and decreasing ductility
