AreX D
Benchtop Retained Austenite Analyzer
Benchtop X-ray diffractometer for fast determination of retained austenite in steels in compliance with ASTM E975-03.

About the AreX D
AreX D is the first benchtop diffractometer designed for the fast, accurate and easy determination of Retained Austenite in compliance with ASTM E 975-03 Standard practice for x-ray determination of Retained Austenite in steel with near random crystallographic orientation.
Phase transformation – in critical and structural steel component – is a very sensitive and important parameter to be evaluated since mechanical and physical properties of steels depends on phase composition.
In many industrial processes, determination of Retained Austenite is requested at very low concentration and with a great accuracy. Traditional metallographic investigation by chemical etching and optical determination of Retained Austenite is in many case ineffective due to the low accuracy and sensibility of this method.
Accurate measurements of retained austenite content is essential during the set up and control of many heat treatment processes as well as plays a great role in Additive Manufacturing processes.
AreX Desktop is a fixed angular range X-Ray Diffractometer equipped with the most modern technical features which grant accuracy, precision, safety and easiness of use, especially designed for quantitative determination of Retained Austenite, manufatured in a desktop version.
X-Ray Diffraction (XRD) is considered the most accurate method available that can accurately determine retained austenite levels down to 0.5%. The integrated intensities of the austenite (220) and (311), and the ferrite (200) and (211) diffraction peaks are measured on the AREX diffractometer. The use of multiple diffraction peaks minimizes the effects of preferred orientation and allows interference from carbides to be detected.
AreX is the unique instrument able to guarantee compliancy with the ASTM E 975 – 03.
Thanks to AreX innovative concept, Retained Austenite volume percentage can be measured in few minutes, just placing the sample and pressing start button. Typical Measuring time is 180 seconds.
Documented applications
Quantitative determination of retained austenite content in heat-treated steels by x-ray diffraction has provided a reliable mean of controlling properties and ensuring quality.
Using “ASTM E 975-03 Standard Practice for X-ray Determination of Retained Austenite inSteel with Near Random Crystallographic Orientation” along with the AreX D, Desktop Retained Austenite issues can be easily monitored and controlled.
- X-Ray Diffraction is considered the most accurate method of determining the amount of retained austenite in steels.
