the set of standard sizes in which materials are available, as well as the format e.g. powders, granules, sheets etc.
Stock forms
2 of 25
associated with how a material reacts to an external force.
Mechanical properties
3 of 25
associated with the actual make-up or structure of the material.
Physical properties
4 of 25
the ability to withstand being crushed or shortened by pushing forces.
Compressive strength
5 of 25
the ability to resist stretching or pulling forces.
Tensile strength
6 of 25
the ability to resist abrasive wear such as scratching, surface indentation or cutting.
Hardness
7 of 25
the ability to absorb impact force without fracture.
Toughness
8 of 25
a material comprised of two or more different materials, resulting in a material with enhanced properties.
Composite
9 of 25
a material whose physical properties change in response to an input or change in the environment, such as electricity, pressure, temperature or light.
Smart material
10 of 25
a material developed through the invention of new or improved processes, for example as a result of man-made materials or human intervention.
Modern material
11 of 25
a metal containing mostly iron and carbon.
Ferrous metal
12 of 25
a metal which does not contain iron.
Non-ferrous metal
13 of 25
a metal made of two or more metals, or combining two or more elements, one of which must be a metal.
Alloy
14 of 25
a material that can be repeatedly reheated and reshaped.
Thermoplastic
15 of 25
a material which when heated undergoes a chemical change whereby the molecules form rigid cross links. Cannot be reheated and reshaped, even at very high temperatures.
Thermosetting polymer
16 of 25
materials which at room temperature can be deformed under pressure, and then upon release of the pressure will return to their original shape.
Elastomer
17 of 25
improved tensile strength and hardness in the localised area when a metal is cold worked.
Work hardening
18 of 25
heating work hardened metal and very slowly cooling it, making it easier to work by making it less brittle and more ductile.
Annealing
19 of 25
a process for hardening the surface of steels with less than 0.4 per cent carbon content.
Case hardening
20 of 25
changes the chemical composition of the surface of low carbon steel so it absorbs more carbon and increase surface hardness.
Carburising
21 of 25
rapid cooling of a heat-treated metal.
Quenching
22 of 25
heating medium or high carbon steels to a given temperature, rapidly cooling via quenching and then heating to a set temperature to remove excess hardness.
Hardening and tempering
23 of 25
the colour seen on metal that indicates the temperature at which brittleness is removed.
Tempering colour
24 of 25
the temperature at which the atoms of carbon and steel mix freely before bonding together to become a solid.
