The production of a magnetic field when strain is applied or a change in dimension when a magnetic field is applied to what material ?

When atoms in materials move away from their nearest neighbours by sliding and making bonds with other atoms - this is known as?

The number of a product that is made can have more influence on the cost than the design on the type of material used.

Manufacturing is concerned mainly with shape changing

Melting of a material and control of its shape while it solidifies is referred to as:

Some examples of intrinsic semiconductors are:

One big advantage of Thermoplastic polymers is that they can be remelted and recycled, while thermosetting polymers cannot.

The atoms of the same element that have a different number of neutrons in their nucleus and therefore a different atomic mass are called :

Metals. Ceramics. Semi-conductors. Polymers - form part of what materials ?

Ionic materials are characteristically hard and brittle and melt at high temperatures.

Iron. Chrome. Tungsten. Titanium - have which structure?

Ionic bonding is directional and covalent bonding is non-directional.

Lack of grain boundaries and crystallographic structure renders metallic glasses extremely strong.

Polymers (often called plastics) are substances composed of long-chain repeating molecules. Bands between the atoms in the chain are strong. Where the bond is much weaker the following polymers are created.

Some metallic alloys, when cooled very rapidly, do not have time to crystallise and form amorphous structures, these structures are called :

Ionic bonding is directional and covalent bonding is non-directional.

Material properties are not dependent on the composition and the conditions of a particular casting process but on the conditions of the material prior to melting.

Materials cannot be made transparent - unless the metal is thinner than the wavelengths of visible light.

Properties and performance of engineering materials depend mainly on?

Materials that can have more than one structure are called:

The main advantage of shape memory alloys is that they function without any input of external energy (except changes in temperature and pressure)

The most common composites used today in engineering consist of high strength crack sensitive materials such as:

Nano-materials are available in:

The elastic modules of materials - ????? as temperature increase.

Materials that do not crystallize are called :
