The increase in strength observed during cold work or strain hardening is primarily due to a vast increase in the number or amount of: dislocations If we deform a metal in successive increments the yield strength will incrementally: increase If a small amount of cold work produces a large increase in strength, the strain hardening coefficient, n, would be ___. high Cold work strengthening is highly effective for metals with this crystal structure: FCC A flat plate of meta...

This type of bonding requires two different types of atoms (an electron donor and an electron receiver) Ionic Materials with this type of bonding can exhibit both high strength and high ductility Metallic 00:40 01:31 Bonds of this type tend to be "directional", and the limited number of nearest neighbors often leads to light weight (low density) materials Covalent Materials with this type of bonding have valence electrons that are free to "wander" throughout the s...
