EBSD Post-processing Software

Collecting good quality data is only the beginning of any complete EBSD analysis. The HKL CHANNEL5 system provides all the necessary tools to process comprehensively the data in any format desired. Each software module performs a specific task, but they are all interconnected via the data management module, Project Manager.

Tango - Orientation map display and manipulation software

Mambo - Pole figure and inverse pole figure software

Salsa - ODF and MODF calculation and display software

Twist - Phase creation software

Tango is a sophisticated software module designed for the sole purpose of manipulating orientation maps. The flexibility of Tango allows you to display each map in many ways and to extract whatever information is important to you. This includes grain sizes, texture data, boundary characteristics, phase distributions and recrystallised fractions.

All of the conventional methods for displaying EBSD mapping data are complemented by an extendable library of map components: many are supplied as standard, but if you wish to define specialised components for your data, Tango provides the facility to create them.

Key Features:

Advanced noise-reduction facility
Customised map creation by overlaying individual map components
Grain size analysis (linear intercepts, grain area, diameter, elliptical fit)
Misorientation profiles along straight lines in the maps
Advanced subset selection based on any map feature (e.g. an area, a specific grain size, a Taylor Factor range etc.)
Legend with histogram display for all map components
Data and graphic export facility in many formats
Extendable library of map components, including:
Pattern quality, Pattern misfit
Orientation colouring (Euler angle, "unit-triangle", RF-vector)
Any user-defined texture component
Strain contouring component
Open map component (via DLL)
Grain and sub-grain boundaries
CSL and special boundaries
Phase boundaries
Phase colouring
Deformed / recrystallized fraction component
Schmid and Taylor factor
EDS counts display

The physical properties of many samples are dependent on the common alignment of particular crystallographic directions: one of the easiest ways to view this is to use pole figures or inverse pole figures.

Mambo is an advanced pole figure program that provides all the features necessary to examine preferred crystallographic orientations in samples analysed using EBSD. However, not only can Mambo analyse orientation data, but it can also be used to study misorientation data. The rotation axes associated with every boundary in the sample can be plotted in either sample or crystal coordinates, thus helping to identify the nature of any special boundaries.

All displays in Mambo can be contoured using advanced contouring algorithms, providing density and contoured displays as required. Mambo is the perfect tool for viewing EBSD data in pole and inverse pole figures.

Key features

Pole figures and inverse pole figures for all 11 Laue groups
Display of misorientation axes with respect to sample coordinate system as well as crystal coordinate system
(axis/angle pair analysis)
View data as scattered data points, density and/or contour lines
Stereographic & equal area projection
Pole plots display
Kearns factor (f-factor) calculation
Advanced subset selection based on specific orientations
Graphic export facility in many formats

Sometimes a pole figure is not enough. The mathematical calculation of an orientation distribution function (ODF) provides, however, a complete description of the texture in your sample.

Salsa can calculate ODFs using several standard methods, and then provides all of the display options necessary for easy interpretation of the results.

Whether you require 3-D plots of the complete Euler space, serial sections or even single density profiles, Salsa provides you with the necessary tools. And, as misorientations and orientations are mathematically equivalent, Salsa also calculates misorientation distribution functions (MODFs).

Key Features

Display of EBSD orientation data in Euler space, as orientations (ODF) or misorientations (MODF)
Distribution function

ODF calculation algorithms

Series expansion method
Gaussian kernel estimation

Display modes

Scattered data points
Density colours

Creation and display of any ideal orientation, e.g. Goss or 100 fibre
Advanced subset selection of specific orientations
Data and graphic export facility in many formats

Before AZtec can index an EBSP, it needs to know which lattice planes in the crystal structure produce the most intense diffraction bands. Although such "reflector files" for many of the most commonly analysed phases are supplied with AZtec, you may sometimes want to collect EBSD data from a "new" phase.
Twist is an easy-to-use software module that allows you to generate reflector files for new phases, regardless of their symmetry, using atomic position data and an advanced kinematical diffraction theory.

Key Specifications:

Simple, step by step procedure to create a new reflector file
Equivalent atom generation (Wyckoff)
Search facility for space group symbols
3D animation of unit cells
All 11 Laue and 230 space groups supported
Reflector intensity calculations based upon kinematical electron diffraction theory

Project Manager is the central hub of the CHANNEL5 data processing software, controlling the data management and communicating with all the other software modules (Tango, Mambo and Salsa).
However, it is much more than just a data management program, as it provides many other tools for the analysis and display of EBSD data. These range from a 3-D crystal viewer to management of CHANNEL5's unique subset selection facility, all allowing greater flexibility and control during your data processing.

Project Manager is supplied as standard with all CHANNEL5 systems, and includes the following key features:
