Phase-Mapper: A Human-
Machine Integrated Platform
In this section, we present the Phase-Mapper plat-
form workflow, which includes visualizing and ana-
lyzing an instance file, setting the solver framework,
analyzing the solution, and using that analysis to
update the solver framework. The design objectives
were simple: create a practical application that seam-
lessly connects a visualization system with a power-
ful solver that allows for interactive and large-scale
use. The main features of Phase-Mapper are the visu-
alization tools and the solver interface. The interface
of the application can be seen in figure 4.
With Phase-Mapper, both the input materials sys-
tems and generated solutions can be visualized in the
same application. When an instance file of a materi-
als system is uploaded to the system, the visualizer
will generate a composition map, which illustrates
the varying compositions of elements for all sample
points. The user can freely inspect the XRD patterns
of each sample point, as well as the heatmap of XRD
patterns for a slice of sample points. A slice heatmap
example is shown in the top left plot of figure 4,
where a selected slice is indicated by the red data
points. The heatmap plot on the top right of figure 4
represents the XRD patterns of the sample points in
the slice.
When the solution files are loaded into the application, either uploaded by the user or generated by
Figure 4. Screenshot of the Phase-Mapper Web Application.
Displayed in the top left is the Nb-Mn-VO system in composition space. Each dot corresponds to an XRD measurement. The dots highlighted in red correspond to selected XRD measurements. The top right plot displays the heatmap of the selected data points’ XRD patterns,
that is, it visualizes the XRDs for all red sample locations in the top left panel. The bottom left plot shows the basis phases found in the
loaded solution of a particular data point. The bottom right plot shows the phase fields for the system.
