Electron Backscatter Diffraction (EBSD) System - AZtecHKL

Accurate:

• Powerful new AZtecTru-I solver engine gives you the best ‘out of the box’ results in real-time

Fast:

• An intelligent optimisation process, you can concentrate on your results and not how you collect them

Integrated:

• EBSD and EDS integration, combines Tru-Q™ and Tru-I™ for phase identification, plus combined EDS and EBSD real-time mapping

Innovative:

• AutoLock provides predictive and reactive drift correction for simultaneous EBSD and EDS data collection

Flexibile:

• Work the way you want to, incorporating automated features and advanced manual settings

Combining the Nordlys detectors and AZtecTru-I ensures that you collect the best quality patterns and solve them accurately, reliably and automatically.

Collect high quality patterns which are essential to obtaining accurate EBSD results.

• AZtec has an optimised system design, for collection of excellent patterns even at high speeds or high binning
• The signal strength and noise are quantified as a measure of pattern quality

• Achieve higher hit rates, with no loss of data validity
  • Band detection and indexing algorithms in Tru-I build on the success of Channel 5 to take EBSD analysis to the next level

• Successfully analyse difficult samples, and distinguish phases with closely related structures and different unit cell sizes - see the real detail in your sample

• More accurate analysis at low kV and when distinguishing closely related structures
  • Use the width of the Kikuchi band when solving patterns
    • For accurate analysis at low kV when the Kikuchi bands are broader
    • Important where high spatial resolution nanoanalysis is required
    • Correctly distinguish closely related structures

• Accurately identify difficult to distinguish phases using Advanced Fit
  • Secondary, advanced solving technique for super high precision orientation data
  • Speed now optimised for everyday applications
  • Assisted by the excellent pattern quality of Tru-I

Pattern collection and solving are performed in real-time

AutoCal

• At installation the engineer will perform a suite of initial calibrations at a range of working distances.  A series of patterns are collected at each working distance at different detector insertion positions and the pattern centre and detector distance are calculated.  When the system is being used, the initial calibration results are interpolated using geometric calculations to predict the precise geometry for any specimen height and detector insertion.
• Calibration is therefore seamless and automatic. AutoCal provides the user the convenience of working at different specimen and detector positions without having to do time-consuming recalibrations.

AutoLock

• AutoLock is an integrated drift correction tool that corrects EBSD and EDS data simultaneously, resulting in the most accurate maps.
• Unique blend of predictive and reactive drift correction routines
• Corrects drift on tilted and untilted samples
• Essential for high magnification nano-scale EBSD

HKLNordlys EBSD Detectors

An essential part of EBSD analysis is the acquisition of high quality diffraction patterns. Sometimes the emphasis is on the speed of data acquisition, whilst at other times data accuracy is paramount.

The HKLNordlys range benefits from an optimised hardware design delivering superior performance for every application.

HKLNordlysNano

Sensitivity is a primary measure of detector performance. The HKLNordlysNano detector offers enhanced throughput coupled with high spatial and angular resolution.

 
Accurate phase identification

• Discrimination of materials with very similar crystallographic lattice parameters
• The highest resolution uses the full 1344 x 1024, CCD array to digitise EBSP’s
• Coupled with Advanced Fit software, it is possible to reliably determine orientations down to 0.3deg
• Correct identification of orientation in pseudosymmetric materials with c/a ratios as low as 2%
• Designed for data collection using low probe currents requiring only 0.5nA to operate. It is ideal for:
• Tungsten or LaB6 SEMs operated in high spatial resolution mode
• Cold FE SEMs
• Thermal FE SEMs that operate with low probe currents

 HKLNordlysMax

The HKLNordlysMax is a new generation EBSD detector offering high speed coupled with the capability to collect data at high temperatures

Superior optics enable ultra fast EBSD analysis

• Data acquired and solved at 640Hz with 98% hit rate

Designed for dynamic studies

• Suitable for all types of dynamic studies, including in-situ tensile experiments
• Incorporates an integrated infra-red (IR) filter for data collection during in-situ heating experiments
• High sensitivity compared to conventional high temperature phosphor screen

Post-processing

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.
