Occurs in some metals, r certain stainless steel, aluminum, and copper alloys, at ambient temperature after solution heat treatment,
Age hardening
Alloy
Anistropy
Is a substance with metallic properties, composed of two or more elements of which at least one is a metal.
Age hardening
Alloy
Anistrophy
Is a tendency to fracture without appreciable deformation. See ductility
Anisotropy
Brittleness
Alloy
Is the characteristic of exhibiting different properties when tested in different directions (as tensile strength "with the grain" or "across the grain").
Anisotropy
Alloy
Brittleness
Is one in which a specimen, supported at both ends as a simple beam, is broken by the impact of a falling pendulum.
Brittleness
Damping capacity
Charpy test
Is brittleness of metals at ordinary or low temperatures. Cold working is the process of deforming a metal plastically at a temperature below the recrystallization temperature.
Ductility
Cold shortness
Ductility
Is the ability of a material to absorb or damp vibrations, which is a process of absorbing kinetic energy of vibration owing to hysteresis.
Ductility
Temper
Damping capacity
Stiffness
Is a loss of carbon from the surface of steel, occurring during hot rolling, forging, and heat treating, when the surrounding medium reacts with the carbon
Izod test
Decarburizatrion
Lever beam
Is that property that permits permanent deformation before fracture in tension.
Ductility
Malleability
Killed steel
Have the same properties in all directions. (Wood has a grain; rolled steel is not isotropic.)
Isotropic test
Isotropic
Isotropic material
Is broken by the impact of a falling pendulum. The energy absorbed in breaking the specimen is a measure of the impact strength.
Malleability
Killed steel
Annealing
Is a material's susceptibility to extreme deformation in rolling or hammering. The more malleable the metal, the thinner the sheet into which it can be formed (usually cold).
Malleability
Killed steel
Annealing
Is the extension in the vicinity of the fracture of a tensile specimen, expressed as a percentage of the original gage length
Percentage stress
Percentage elongation
Percentage reduction of area
Is the smallest area at the point of rupture of a tensile specimen divided by the original area.
Percentage stress
Percentage elongation
Percentage reduction of area
Exclude mechanical properties, and are other physical properties such as density, conductivity, coefficient of thermal
Physical properties
Poison's ratio
Stiffness
Is the ability of a metal to be deformed considerably without resistance. rupture. In a plastic deformation, the material does not return to its original
Physical properties
Red shortness
Plasticity
Is the ratio of the lateral strain (contraction) to the shape. See elasticity. Longitudinal strain (extension) when the element is loaded with a longitudi nal tensile force.
Physical properties
Poison's ratio
Stiffness
Is a brittleness in steel when it is red hot. Relaxation, associated with creep, is the decreasing stress at a constant strain; important for metals in high-temperature service.
Temper
Poison's ratio
Red shortness
Are those not due to applied loads or temperature gradients; they exist for various reasons, as unequal cooling rates and cold
Wrought steel
Residual stress
Heat treatment
Is the ability to resist deformation. It is measured by the modulus of elasticity in the elastic range; the higher the modulus, the stiffer is the material.
Temper
Stiffness
Wrought steel
Is a condition produced in a non-ferrous metal by mechanical or thermal treatment: for example, annealed temper (soft), hard temper, spring temper.
Malleability
Killed steel
Temper
Refers to the results of a transverse bend test, the specimen being mounted as a simple beam; also called rupture modulus.
Lever beam
Transverse skills
Transverse strength
Is steel that has been hammered, rolled, or drawn in the process of manufacture; it may be plain carbon or alloy steel.
Wrought steel
Killed steel
Mechanical steel
Is an operation or combination of operations involving the heating and cool ing of metal or an alloy in the solid state for the purpose of altering the properties of the material.
Hardening
Heat transfer
Heat treatment
Is a change in a metal by which its structure recovers from an unstable or metastable condition that has been pro duced by quenching or cold working.
Aging
Izod
Homogeneous
A comprehensive term, is a heating and slow cooling of a solid metal, usually done to soften it Other purposes of annealing include those of altering the mechanical and physical properties,
Annealing
Malleability
Malleablizing
Is the heating of certain steels above the transformation range and then quenching, for the purpose of increasing the hardness.
Normalizing
Annealing
Hardening
Is an annealing process whereby combined carbon in white cast iron is transformed wholly or in part to temper carbon.
Normalizing
Malleabilizing
Spheroidizing
Is the heating of an iron-base alloy to some 100°F above the transformation range with subsequent cooling to below that range in still air at room temperature.
Normalizing
Malleabilizing
Spheroidizing
Is any heating and cooling of steel that produces a rounded or globular form of carbide.
