Question

During the recrystallization of a cold-worked material, which of the following statement(s) is (are) true?

1,The electrical conductivity is recovered to its precold-worked state.

2,There is a significant reduction in the number of dislocations, to approximately the number found in the precold-worked state.

3,Grains with high strains are replaced with new, unstrained grains.

4,The metal becomes more ductile, as in its precold-worked state.

5,There is some reduction in the number of dislocations.

6,All of the internal strain energy is relieved.

7,The thermal conductivity is recovered to its precold-worked state.

2,There is a significant reduction in the number of dislocations, to approximately the number found in the precold-worked state.
