Apa itu Dislokasi Ara?

Dislocations are defects with in a crystal structure tont allow demformation to convelr at lower stresmers. They are fundatal to plastic deformation, enabling materials to bend or strearch withoutrefraturing. The movemenitenitenof locationes transcution.

How Grain Boundaries Affect Dislocation Movement

Grain boundariees can either hindr or promote dislocation motion, depending on their characterstics. Their effects include:
