Complete automated instrument to determine Retained Austenite

AreX L is an outstanding automated instrument to measure Retained Austenite in compliance with ASTM E 975 -03.

Accurate measurement of the retained austenite levels is important in the development and control of heat treatment process in steel industry.

X-Ray Diffraction (XRD) is considered the most accurate method available that can accurately determine retained austenite levels down to 0.5%.

Mechanical and physical properties of steels depend on phase composition. Phase transformation in critical and structural steel component is sensitive and important parameter to be evaluated.

Extremely low concentration and accurate determination of Retained Austenite is required in industrial processes. Traditional metallographic investigation like chemical etching and optical determination of Retained Austenite are often ineffective due to the low accuracy and sensitivity of method.

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.

AreX Laboratory is a fixed angular range high-accuracy X-Ray Diffractometer. Modern precision AreX L is safe and easy to use. Designed for the quantitative determination of Retained Austenite confirms to ASTM E 975 03 and factory 4.0 specifications.
