    This is absolutely fascinating!
    As you have been giving your presentation I have been taking notes thinking of how this technique can be used to supplement and support the critical technical data used to specify steels in the manufacturing standards to include a quantitive representation of the overall quality using chemical composition as a function which allows for analysis of the effects and interactions each alloying element on the microstructure has including:
    Homogeneity
    Ratios of constituents
    Grain boundary discontinuities/defects
    Plane symmetry
    Precipitates
    Segregation patterns of alloys
    (fatigue analysis)
    Theoretical vs Pratical(actual) :
    Strength
    Elasticity etc
    I have been a fabricator welder for many years then became an inspector for a while and I have a passion for engineering.
    I would love to know if this type of approach could be modelled and used as a tool/technique in the certification process of steels which require high degrees of testing and inspections for approval ?
    Ultimately leading to an inclusion of this technology to the certification process of steels and possibly even further into WPQR's?
    Thank you for your time reading this and would love to hear back from you.
    Regards

      The amount of material examined in any high-resolution technique, such as the atom probe, is incredibly small. It would not therefore be able to provide representative data on the dimensional-scales associated with your query.
