 ``xrdfit`` is a Python package we have developed for a faster fitting of diffraction peaks in SXRD (and XRD) spectra, which can be used for datasets containing many thousands of patterns. It is intended as an easy to use tool which enables automated, repeatable identification of peak positions and profiles in spectra with multiple individual or overlapping lattice plane peaks. The features of  ``xrdfit`` are shown schematically in \autoref{fig:figure1}. ``xrdfit`` uses the Python package ``lmfit`` [@Newville_2014] for the underlying fitting. Features are included for selecting different 'cakes' of data and automating fitting over many spectra, to enable tracking of peaks as they shift throughout the experiment. By analysing how different lattice plane peaks change during simulated processing, as can be seen in \autoref{fig:figure2}, the transformation and micromechanical behaviour of the material can be understood.

-``xrdfit`` is designed to be accessible for all researchers who need to process SXRD (and XRD) spectra and so does not require a detailed knowledge of programming or fitting. The package has been used for the analysis of data taken during the hot deformation of a two-phase titanium alloy, which is presented in an article currently in press [@Daniel_2019], and will be used for future studies investigating the high temperature processing of metals in our research group. We hope that its public release will allow other researchers to benefit from fast data fitting, reducing the effort required to analyse their experimental data.

The shifts of the peak can be used to calculate elastic lattice straining in the hexagonal close-packed (hcp) lattice, as well as measure the thermal contraction on cooling.\label{fig:figure2}](figure2.eps)
