Definition and Importance of Materials Science
What is Materials Science?
Study of material properties, behavior, and structure.
During the 1903, Al-Cu alloys was use with aircrafts engine, what Metal was not used as material for an aircraft engine because they are "were too heavy to lift of the ground"
Iron (Fe) engines
It is a non-metallic, inorganic material that are brittle, and typically have high melting points. They are used for their insulating properties, hardness, and heat resistance.
Ceramics
The application of science and technology is the manipulation of matter at the atomic and molecular level.
Nanotechnology
True or False: Copper is the primary material used in the fabrication of integrated circuits.
False
Why study material reactions to stress and temperature?
To design safer and more durable materials.
During the 1200BC, what are the two steps of Steel Hardening?
Quenching and Tempering
It is a type of material that are excellent conductors of electricity and heat and typically has shiny appearance.
Metals
An area of material science that examines the chemical and physical characteristics of metallic elements and their intermetallic complexes, also known as ____.
Alloys
Which of the following is NOT a key characteristic of a biocompatible material?
a) Sensitive to bodily fluids
b) Non-carcinogenic
c) Shouldn't trigger immune responses
a) Sensitive to bodily fluids
Examples of materials studied in Materials Science?
Metals, polymers, ceramics, composites, semiconductor
mentioned earlier that the production and heat treatment of ____ alloys and ____ alloys are among the greatest technological developments in human history. What are the those two alloys?
Fe-C alloys and Al-Cu alloys
This type of materials are essential in modern electronics for controlling electrical signals. Examples are Silicon, Germanium, Gallium Arsenide.
Semiconductors
In the context sub-field of materials science, what does the "crystallography" refer to?
Greek words crystallon= cold drop/frozen drop, graphein= write
In aerospace, this composite material has many advantages, including its lightweight, strength, and resistance to corrosion. It is made by combining carbon fibers with plastics. What is this material called?
Carbon-fiber reinforced polymer (CFRP)
