    Abstract

    A standard practice (ASTM E 975) was developed by Task Group E04.0602 for the X-ray diffraction determination of retained austenite in steel. Results of interlaboratory studies of retained austenite samples performed before and after the practice was developed are described. The final interlaboratory study using ASTM E 975 and ASTM E 173 as a guide to the study resulted in an estimate of repeatability within the same laboratory of 3% retained austenite for a 95% confidence limit, and an estimate of reproducibility between laboratories of 4% retained austenite for a 95% confidence limit.
