Material Properties Flashcards
properties referring to the sound transparency i.e. ability of a material to let the radio waves pass, absorb them or reflect them
acoustical properties
property of a metal to combine with another material for instance a metal in order to get a blended materi- al
- ->alloyed
ex. : Copper shows excellent alloying properties
alloying property
property of a material, which does not bend under strain and breaks easily when a mechanical shock is ap- plied for example. It is the degree at which a material breaks when a mechanical force is applied on to (e.g. tensile forces, bending forces, compressive forces, shear forces, torsion forces)
–> brittle/fragile
brittleness
Definition 1
a substance that enables a chemical reaction to proceed at a usually faster rate or under different conditi- ons (as at a lower temperature) than otherwise possible
Definition 2(none)
catalyst
Properties referring to the ability of a material to withstand chemical attacks (exposure to corrosive sub- stances e.g. acids, alkalis) or to react when exposed to certain conditions or to other materials
chemical properties
Definition 1
ability of a material to burn
ex.: Unlike stone, gasoline is combustible as well as wood
Definition 2
property of a material that can easily catch fire und burn –> combustibility
combustible
electrical conductivity
–> electrically conductive
thermal conductivity
–> thermally conductive
conductivity
property of a material to deform when a mechanical force (e.g. compressive force, tensile foce, shear force) is applied to it…before it breaks.
–> ductile
ductility
property of a material which can strech under strain but recovers its original shape as soon as the tensile force applied to it is released
–>elastic
elasticity
Ability of items or material to either allow the passage of electrons or resist the electrical current (‘resistivity’).
electrical properties
adj describing the property of a material which is resistant to damage from fire
fireproof
property of a material which…. –>flexible
flexibility
property of a material which can resiste the impact of another material –>hard
hardness
property of a material which swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescents are typically used in passive fire protection
intumescence
property of a material to be shapped
malleability
Properties of a material or an item to withstand forces (tensiles forces, compressive forces, torsion forces, shear forces, flexion bending forces, bending forces…)
e.g. resilience, elasticity, plasticity, toughness, brittleness
mechanical properties
ability of a material to pass, modify or reflect light (optical waves) or changes depending on the waves
optical properties
Properties referring to its density surface texture of a material and its size (length, width, depth, height, dia- meter, radius, and circumference)
Physical properties of a material
property of a material which can deform under strain whereby undergoes a permanent change in shape and size when the strain exceed a certan value (yield value)
–> plastic
plasticity
material has many small voids (holes) so water or air gets through it. –> porosity
porosity
refers to the property of a material that can recover its original shape or/and is not destroyed when different types of force are applied to it and afterward released. It is is a property of a ma- terial which can deform in follow of a central force and recovers its original shape (i.e. possibly bouncing back).
resilience or resiliency
….
semiconductivity
property of a material which doesn’t show much resistance to the impact of another material (i.e. can be bent easily, can deform and cannot withstand mechanical shocks for instance)
–> soft
softness
property of a material which
–>stiff
stiffness
Properties referring either to the ability of material to conduct heat or insulate from ambient temperatures
Thermal properties
–> tough
toughness
material, that can let pass light partially but the material is not transparent, e.g. wax or sheets
translucency
property of a material which can let visible images passes through –>transparent
transparency
