Dislocation density

[@nguyenngocvinhxd]

Thanks for the video. However, can you perform an example that shows the determination of dislocation density from the TEM image? Thanks!

Sir, how to measure total length of dislocation?

[@SohailAhmad-xo1ee]

sir please let me know that how to find TDD of a sample i.e 2*109cm-2

Ye real me step surface dikhta h kya?

[@MuhammadHussain-ky1fb]

nice

[@rishikakhanna6073]

Sir in a crystal, length of dislocations could be different for different dislocations if we consider that they can end in a node(where disslocations are intersecting), so in that case will dislocation density be different for each dislocation ? or we always consider dislocation length to be equal to length of edge of crystal?

[@introductiontomaterialsscience]

We usually consider the average dislocation density. This by definition is total length of the dislocation divided by the total volume of the sample.

[@rishikakhanna6073]

Okay, Thank you.

[@nirvikbanerjee1074]

Sir in some books it is written as 10 ^-6 in case of dislocation density is it correct

[@rajeshprasad101]

The value will depend upon the units, whether it is in cm^-2 or m^-2.
