Materials Engineering (Actual) Exam Graded A+
Materials Engineering - ANS-The understanding and modification of the structure
and properties of materials to improve the performance and processing of the
material, finding new uses for existing materials, developing better manufacturing
for existing materials, and often specialize in a specific material.
Materials Science - ANS-Research and explore new materials and their properties.
American Society for Testing and Materials (ASTM) - ANS-Develops material testing
standards, with over 30,000 members worldwide.
MIS, MRS, NACE International - ANS-Other organizations for ceramics, plastics, and
metals.
Types of Materials - ANS-Metals, Ceramics, Polymers, Composites.
Metals - ANS-Most common element, have crystalline atomic structure, high
material strength, good conductors of heat and electricity, malleable, inorganic
material. Many are found and mixed with other minerals. Commonly used in alloys.
Natural - ANS-Most pure metals are ______.
Crystalline Structures - ANS-In these structures, the atoms are arranged close
together in a regular and repeating structure.
Ore - ANS-Mixture of metals and minerals; require processing to purify the metal or
remove unwanted minerals.
Alloy - ANS-Metal mixed with one or more elements
Ex:
Brass = Copper + Zinc
Materials Engineers change the properties of these by changing the amount of
individual elements that are used.
Ceramics - ANS-Nonmetallic solids made from inorganic materials, made using a
process of mixing, shaping, heating, and cooling, most have a crystalline structure,
strong in compression (keep their shape and strength), high melting temp. (can
retain heat well), brittle but resistant to wear. Are good insulators and do not
conduct electricity.
Polymers - ANS-Made up of a long chain of small molecules that form a much
longer molecule (often including carbon and hydrogen), organic materials,
noncrystalline, ductile, can be natural or synthetic.
