alloys and composites Flashcards
What is the primary difference between alloys and composites?
The primary difference between alloys and composites is in their compositions. An alloy must have a minimum of one metal in its composition, while composites don’t have any metal components.
What is an alloy?
An alloy is a homogeneous material which can be created by melting two or more elements, of which one is a metal. Alloys tend to have better/more desirable properties when compared to the properties of the constituent substance they are made of.
What is a composite?
Composites are often a combination of two or more elements, but their structure does not include metals. Composites are heterogeneous, in contrast to alloys. Most composites are naturally encountered, while others are engineered.
Can alloys conduct electricity?
Yes, most alloys can conduct electricity.
Can composites conduct electricity?
Generally, composites do not conduct electricity except for polymeric composites.
What is a participatory metal?
A participatory metal, also known as the parent metal, serves as a base metal for the alloying element and is considered an alloying agent for the majority of the substances in an alloy.
What can be the nature of alloying agents in an alloy?
The alloying agents in an alloy can either be non-metal or metal.
What is the contribution or proportion of alloying agents in an alloy?
The contribution or proportion of alloying agents in an alloy is very small.
What are some examples of alloys?
Some examples of alloys are steel, brass, and bronze.
What characteristic do almost all alloys share?
Almost all alloys are lustrous, which can be attributed to the presence of the metallic component in their composition.
What are composites composed of?
Composites are composed of components which have different physical properties.
What are some natural examples of composites?
Natural examples of composites include wood and human body bones.
What is an example of an industrial composite?
An example of an industrial composite is fiberglass.
