It is important to measure retained austenite levels accurately especially in development and control of heat treatment process in steel industry.
XRD is the most accurate way available to 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 Laboratory 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.
It is a unique instrument that able to guarantee compliancy with the ASTM E 975 - 03.
