Plasticity

The ability of a material to be deformed plastically, without rupture or failure. This property incorporates both ductility and malleability.

Ductility

The ability of a material to be deformed plastically under a tensile load without rupture or failure.

Malleability

The ability of a material to be deformed plastically under a compressive load without rupture or failure.

Brittleness

The inability of a material to exhibit plasticity or elasticity.

Elasticity

The ability of a material to return to its original dimension after the removal of a load.

Elastic Limit

Also known as proportional limit or yield point. This is the maximum stress and strain accepted before permanent strain or deformation results.

Elastic Range

The range of deformation within a material where the amount of strain is not proportional to the load applied. This phenomenon is known as Hooke's Law.

Plastic Range

The range of deformation within a material where the amount of strain is not proportional to the load applied. Permanent deformation will result.

Ultimate Tensile Strength

The highest value reached on the stress axis during a tensile test. It is this value which is used to compare strengths of materials for the engineering of a component.

Compressive Strength

The ability of a material to resist deformation under a compressive load.

Tensile Strength

The ability of a material to resist deformation under a tensile load.

Impact Strength

The ability of a material to resist deformation under an impact load.

Fatigue

The phenomenon of the progressive failure of a material due to cyclically induced cracking.

Creep

A slow, plastic deformation within a material, caused by a load that is valued below the material's yield point.

Magnetic Flux Conductivity

The ability of a material to conduct lines of magnetic flux.

Electrical Conductivity

The ability of a material to conduct electron flow.

Thermal Conductivity

The ability of a material to conduct thermal energy.

Melting Point

The temperature at which a material will change from a solid state to a liquid state.

Specific Gravity

The comparison of the weight of a given volume of a material with an equal volume of demineralized water. This results in a ratio as the water is considered having a standard of one.

Density

The mass per unit volume of a material

Colour

The ability of a material to reflect and absorb different wavelengths of light energy.

Thermal Coefficient of Expansion

The change in the physical dimension of a material due to its level of thermal energy.

Oxidation

The combination of an element with oxygen to form an oxide. The physical, chemical and mechanical properties differ from the original element.

Reduction

The removal of oxygen from a compound or oxide to isolate an element.

Corrosion

The undesirable chemical attack on a material. May take the form of an atmospheric, submarine, subterranean or an electrolytic attack.

Hardness

The ability of a material to resist penetration,
directly related to the ultimate tensile strength of some metals such as steel.

Toughness

The ability of a material to resist tearing under bending or tensile loads. Often quantified as, "the area covered by a material's stress/strain curve."

Strength

The ability of a material to resist deformation.

Stress

The internal reaction of an object to an applied external load. May take the form of tension, compression, torsion, shear and bending.

Strain

The deformation (either plastic or elastic) of an abject due to stress.

Face Centered Cubic Structure

The geometric shape and structure of a highly plastic metal such as aluminium.

Body Centered Cubic Structure

The geometric shape and structure of a plastic metal such as iron.

Closed Packed Hexagonal Structure

The geometric shape and structure of a low plasticity metal such as magnesium.

Slip Plane

The plane allowing easy molecular movement within a geometric structure of a metal.

Space Lattice Structure

The primary structure formed by the geometric structures of a metal upon crystallization of the metal.

Grain

The irregular shaped crystals of a metal formed upon crystallization due to boundary line interference of the space lattice structures.

Dislocations

Lines of defective bonding in crystal structure.

Load

The weight supported by a structure or part.

Two Main Factors in Materials

Strength and weight

Force

The influence which tends to cause an object to accelerate or decelerate.

5 Types of Force

Tension, compression, torsion, shear, and bending.

Bearing Strength

A materials ability to resist compression.

Three Types of Hardness Testing

Rockwell, Birnell, and Vikers

Measure of Tensile Strength
