Metallurgy Exam 1
This type of bonding requires two different types of atoms (an electron donor and an
electron receiver) - Answer Ionic
Materials with this type of bonding can exhibit both high strength and high ductility -
Answer Metallic
Bonds of this type tend to be "directional", and the limited number of nearest neighbors
often leads to light weight (low density) materials - Answer Covalent
Materials with this type of bonding have valence electrons that are free to "wander"
throughout the structure (high conductivity) - Answer Metallic
This type of bonding is considered the weakest of the four types listed below - Answer
VanderWaals
The number of "nearest neighbor" atoms in a crystal structure is called the - Answer
Coordination number
In the face-centered cubic (FCC) crystal structure, atoms touch (are in contact) along
the - Answer Face diagonals
The coordination number for a face-centered cubic (FCC) structure is - Answer 12
The stacking sequence of close-packed planes in the face-centered cubic (FCC) crystal
structure is - Answer ABCABC
Which of the following crystal structures does NOT contain close-packed planes -
Answer BCC
The packing factor for structures involving stacked close-packed planes (highest
possible) is: - Answer 74%
Compared to materials with other crystal structures, materials with the HCP structure
tend to - Answer be brittle
Aluminum, copper and silver are typically soft, weak, and ductile metals. These are
characteristics of which crystal structure - Answer FCC
The directions of atom-touching in the FCC structure have the Miller Indices form of -
Answer <110>
Materials that can exist in more than one crystal structure (depending upon the
conditions of temperature and pressure) are called: - Answer Polymorphic
