suggest me some journals to learn about the technique to do and analysis.
Dear Simson Daniel,
Dislocation density can be found out by knowing the grain size, lattice strain and Burger's vector of the material (eg: BV of Al is 0.286 nm)
Lattice strain can be obtained by using XRD peak broadening as-per the Williamson-Hall method.
You may find a reference in Ma et al. "Mechanical behavior and strengthening mechanisms in ultrafine grain precipitation-strengthened aluminum alloy"

Anas
