Introducing PRIAS™ The Pattern Region of Interest Analysis System

New Insight Through Flexible Imaging


PRIAS: The Pattern Region of Interest Analysis System

PRIAS™is a synergistic new imaging technique to visualize microstructure and provide exciting new views of your materials. PRIAS™enables users to quickly characterize materials without requiring full EBSD pattern indexing. Through a novel use of the EBSD camera, PRIAS™provides as many as 25 positional electron detectors to allow unprecedented flexibility in image collection and visualization. Applications of PRIAS™include traditional EBSD materials such as metals, ceramics, semiconductors, and minerals as well as new analysis of plastics and glasses.


PRIAS Imaging simultaneously detects multiple contrast mechanisms:

3 Modes of Operation

PRIAS™
Live:
Dedicated mode for fast microstructural imaging with 25 positional detectors available.
 
PRIAS™ Collection: PRIAS™ data automatically collected simultaneously with EBSD mapping data using 3 preset detectors.
 
PRIAS™ Analysis: Powerful analytical analysis of EBSD pattern intensity distribution coupled with direct correlation with measured crystallographic orientation and phase information. This mode includes full control over detector positioning.



Advanced Image Processing Capabilities

PRIAS™ has a comprehensive toolbox for processing, coloring, and extracting useful information from the images generated from the multiple positional detectors available.

In this example from a dual phase ferrite-martensite steel, orientation and topographic contrast images were selected from the 25 positional detectors. A weighted subtraction approach was used which produced a processed image which highlighted the contrast between the ferrite and martensite phases.

Here multiple display modes are used to illustrate the PRIAS™ imaging options on a deformed steel sample. Greyscale and color images can be created using any of the 25 positional detectors. Both static and dynamic background processing can also be applied.

PRIAS™ detector signals can also be computationally compared, and the difference displayed as greyscale or colored image. This allows quick identification of the grain boundaries and microstructure and can be used for a rapid estimation of grain size. Examples of this are shown above for TiAl and Nickel alloys.


PRIAS™ and Transmission-EBSD

PRIAS™ is also compatible with Transmission-EBSD (T-EBSD), and can provide additional levels of detail from electron transparent samples.

PRIAS™ provides unprecedented flexibility in imaging microstructures. In this example, RGB coloring of a subset of the 25 positional detectors was used to highlight a specific zoned region with a quartz microstructure.

By combining up to 25 positional detectors with flexible image visualization and analysis, PRIAS™ enables exciting new insights into today’s materials analysis.
