All of the internal strain energy is relieved. There is some reduction in the number of dislocations. There is a significant reduction in the number of dislocations, to approximately the number found in the precold-worked state. ✓ The electrical conductivity is recovered to its precold-worked state. The thermal conductivity is recovered to its precold-worked state, The metal becomes more ductile, as in its precold-worked state. Grains with high strains are replaced with new, unstrained grains. thook and Media

Answer 1

During the Recovery of a cold worked material, following Statements are true : All of the Internal strain energy is Relieved There is some reduction in number of dislocations The electrical conductivity is recovered to its precold state The thermal conductivity is recovered to it's pre cold state Graing with high strains are replaced with new, unstacuined grains Metal becomes more duchle as in precold-worked stare
