Question

51. The total length of dislocation line per cubic centimeter in a material.

Answer 1

Dislocation density

It is defined as the total length of dislocation line per unit volume of crystal.

There is another way to find dislocation density : no of dislocation per unit volume

We count the no of dislocation easily through experimental techniques so it's used more often . Both can give different values which are differentiated by the unit of values
