Abstract:

Selected austenite and martensite lines were scanned at 1 degree per minute using an X-ray Diffractometer. The trace of the reflections was recorded on a strip chart recorder. The area under each peak was calculated and the volume percent retained austenite determined for each of five samples. It is indicated that the surface preparation of the sample analyzed has no effect on the results of the analysis. The reproducibility in this procedure was found to vary between plus or minus 3 and plus or minus 5 depending on the method of calculation. Author
