Occurs in some metals, r certain stainless steel, aluminum, and copper alloys, at ambient temperature after solution heat treatment,

Age hardening

Alloy

Anistropy

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 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
