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%.
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.
ARE X 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.
ARE X is the unique instrument able to guarantee compliancy with the ASTM E 975 - 03.
Thanks to ARE X innovative concept, Retained Austenite volume percentage can be measured in few minutes, just placing the sample and pressing start button.
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 ARE X, retained austenite issues can be easily monitored and controlled.
