Dislocation density Measurement

[Murugesan S]

Dear All,

How can I get a dislocation density from the X-Ray diffraction analysis
after the Rietveld Refinement, or any other method to calculate the
Dislocation density from the powder X-ray  data,


please give me your suggestions and notes,

Thanks in advance

With warm reagrds
