GNR AREX L: Precision Retained Austenite Measurement via X-Ray Diffraction
The AREX L is a fixed angular range X-ray diffractometer purpose-built for quantitative retained austenite determination — delivering measurements down to 0.5% in minutes, compliant with ASTM E 975-03.
X-Ray Diffraction is recognized as the most accurate method for retained austenite measurement. The AREX measures the integrated intensities of austenite (220) and (311) and ferrite (200) and (211) diffraction peaks simultaneously — using multiple peaks to minimize preferred orientation effects and detect carbide interference.
With the AREX’s innovative measurement concept, retained austenite volume percentage can be determined in under 5 minutes by simply placing the sample and pressing start. Calibration is included.
