What is Materials Science?
The field that studies, designs, and improves materials for useful applications.
What is materials science and engineering?
The four major classes of engineering materials include metals, ceramics, polymers, and this class.
What are composites?
The materials tetrahedron connects materials, processing, structure/shape, and this fourth area.
What are properties?
A material that returns to its original shape after a force is removed demonstrates this property.
What is elasticity?
Developing recyclable materials and reducing waste addresses this future need.
What is sustainability?
From Stone Age tools to modern medical implants, this field has helped drive human progress.
What is materials science?
This class of materials includes substances such as steel, aluminum, and copper.
What are metals?
Changing the manufacturing method can change a material's internal structure and therefore its this.
What are properties?
The amount of mass contained in a given volume is called this property.
What is density?
Finding alternatives to scarce minerals and improving recycling can help address this challenge.
What is resource scarcity?
Developing a lighter vehicle material that reduces fuel use is an example of solving this type of problem.
What is a technical problem?
This class generally includes materials such as plastics and many synthetic fibers.
What are polymers?
This part of the tetrahedron describes how a material is made, shaped, or treated.
What is processing?
A material's ability to carry an electrical current is an example of this type of property.
What is electrical conductivity?
Materials that can withstand extreme temperatures, corrosion, or wear address this future need.
What are adaptability and resilience?
Developing an affordable, environmentally responsible building material addresses both technical and this
type of problem.
What is a sociocultural problem?
A material made by combining two or more different materials to create improved performance belongs to
this class
What is a composite?
The arrangement of atoms or features within a material is represented by this part of the tetrahedron.
What is structure?
Materials designed to provide specialized or improved performance are often called these
What are advanced materials?
Materials that are stronger, tougher, and more durable while remaining lightweight represent this goal.
What is performance enhancement?
Engineers may consider social, economic, environmental, and ethical effects when developing a new material because technology affects this.
What is society?
An engineer choosing a material for an aircraft would most likely prioritize this combination of
characteristics
What are high strength and low density?
The tetrahedron is important because changing one of its four areas can affect the other three. This
shows that the areas are this.
What are interconnected?
A material that is strong, lightweight, and electrically conductive demonstrates this concept: one material
can provide multiple useful properties.
What is multifunctionality?
Working with engineers, scientists, economists, and communities to evaluate a new material
demonstrates the interdisciplinary nature of this field.
