For BCC crystal structure, which of the following statement is correct? O The BCC crystal system does not achieve the maximum atomic packing in volume, therefore there is no closely packed crystallographic plane in BCC structure. The dislocation slip may not easily be activated by the external axial force, compared to the FCC structrue. For the BCC crystal system, the most closely packed directions are the family of {111}, therefore no matter what crystallographic plane serves as the slip plane, the slip direction should always be one of the {111} directions. The BCC single crystal is much stiffer than the FCC single crystal since it has less possible slip systems. O When the BCC single crystal is under the external axial force, the system [111](110) will be activated for dislocation to slip.

For BCC crystal structure, which of the following statement is correct?
The BCC crystal system does not achieve the maximum atomic packing in volume, therefore there is no
closely packed crystallographic plane in BCC structure. The dislocation slip may not easily be activated by the
external axial force, compared to the FCC structrue.
For the BCC crystal system, the most closely packed directions are the family of {111}, therefore no matter
what crystallographic plane serves as the slip plane, the slip direction should always be one of the {111}
directions.
The BCC single crystal is much stiffer than the FCC single crystal since it has less possible slip systems.
When the BCC single crystal is under the external axial force, the system [111](110) will be activated for
dislocation to slip.
