Specimen characterisation can often be time consuming and requires a highly skilled operator to interrogate the data. At a touch of a button, AutoPhaseMap automatically finds areas of different characteristic composition from X-ray map data, and determines the distribution, area, constituent elements and generates an easy to interpret Phase Image.


AutoPhaseMap is a new way of automatically creating a phase distribution map of a specimen.

During or after acquisition, AutoPhaseMap automatically:

  • Turns X-ray map data into Phase Map data in seconds
  • Calculates and displays:
    • distribution of each phase
    • spectrum and composition for each phase
    • area fraction for each phase
  • Finds phases for all size ranges, including nanomaterials
  • Finds hidden phases, highlighting missing elements which are present in trace amounts

Phase characterisation of an Aluminium Alloy using EDS

The AutoPhaseMap module in the Oxford Instruments’ EDS software, AZtecEnergy, automatically finds areas of different characteristic composition from X-ray map data, and determines the distribution, area, constituent elements and composition of each of these areas or phases. This application note examines how this can be used to characterise an aluminium alloy and its inter-metallic phases.

Phase characterisation of an Igneous Rock and validation of the result using EBSD

The AutoPhaseMap module in the Oxford Instruments’ EDS software, AZtecEnergy, automatically finds areas of different characteristic composition from X-ray map data, and determines the distribution, area, constituent elements and composition of each of these areas or phases. This application note examines how this technique can be used to determine and characterise the phases present in an igneous rock. Finally the results obtained are compared to the phase mapping results calculated from an EBSD dataset collected simultaneously with the EDS acquisition, to validate the result of the AutoPhaseMap method.

Automatic discovery of minor phases

The AutoPhaseMap module in the Oxford Instruments’ EDS software, AZtecEnergy, automatically finds areas of different characteristic composition from X-ray map data, and determines the distribution, area, constituent elements and composition of each of these areas or phases. This application note examines how this technique can uncover previously missed minor phases - even when their constituent elements are not known to be present in advance.

Phase characterisation of nanoscale intermetallic phases in a Ni-based alloy

AutoPhaseMap software in AZtecEnergy automatically finds areas of different characteristic composition from X-ray map data, and determines the distribution, area, constituent elements and composition of each of these areas or phases. This application note examines how this can be used to investigate the chemistry and distribution of nanoscale intermetallic phases in a Ni-based alloy which are on the scale of 150-1000 nm.

Classification of igneous rocks using automatic phase mapping with AZtecEnergy

The AutoPhaseMap module in the Oxford Instruments’ EDS software, AZtecEnergy, finds areas of different characteristic composition from X-ray map data, and determines the distribution, area, constituent elements and composition of each of these areas or phases. This application note examines how this technique can be used to determine the modal percentages of different minerals in an igneous rock, and from this result classify its type.
