Dislocation climb is temperature dependent phenomena and present in both edge and screw dislocation.

Dislocation climb is temperature dependent phenomena and present in both edge and screw dislocation. Correct Answer False

Climb is only possible in edge dislocation, not in screw dislocation because there is no extra half plane present in screw dislocation.
