AreX D


The Arex S is the first desktop X-Ray  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.

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

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.

X-Ray Diffraction is considered the most accurate method of determining the amount of retained austenite in steels.

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.
