3) Failure due to repeated loading and unloading is called ______Fatigue____.

4) The combination of a crystallographic plane and direction where slip occurs is called a

________________________.

5) The formation of a new set of strain-free grains in a material that has been cold-worked is called

__recrystalization__.

6) The {110} 111 slip system is valid for materials with the___BCC___ structure.

1) The Hall-Petch equation shows that metal yield Strenth is a function of average grain

size.

2) A nucleation event that occurs independently of (i.e. without) a pre-existing surface is called

Homogenous nucleation.

3) Failure due to repeated loading and unloading is called Fatigue .

4) The combination of a crystallographic plane and direction where slip occurs is called a Slip System

5) The formation of a new set of strain-free grains in a material that has been cold-worked is called recrystalization

6) The {110} 111 slip system is valid for materials with the BCC structure.

7) Total length of all dislocations divided by a unit volume is the Dislocation Density.

8) Alloys with a solute concentration higher than the eutectic composition are called Hypereutectic alloys.

9) The material property that describes the ability of a material with a flaw to resist crack

propagation is called Fracture Toughness.

10) The BCC phase of iron that is stable at room temperature is called Alpha iron (Austenite)
