  Determination of lattice misfit and microstructural parameters of the
coherent precipitates in Ni based alloy Inconel-625 is a challenging problem as
their peaks are completely overlapping among themselves and also with the
matrix. We have used a novel X-ray diffraction technique on the bulk samples of
Inconel 625 at different heat-treated conditions to determine the lattice
parameters, the lattice misfit of the coherent precipitates with the matrix and
their microstructural parameters like size and strain.
