This book presents a detailed account of the preparation and characterization of a Standard Reference Material (SRM) intended for the calibration of x-ray diffraction equipment used in determining the amount of retained austenite in hardened steels. The SRM was produced using powder metallurgical techniques and involved blending 30 percent by weight AISI type 310 stainless steel powder (austenitic) with AISI type 430 stainless steel powder (ferritic). The author describes the steps involved in the preparation of the compacts, including pressing, sintering, and vacuum annealing. The characterization of the SRM included x-ray fluorescence spectrometry to determine the nickel content and quantitative microscopy measurements to determine the volume percentage of austenite. A calibration curve was established using 19 compacts randomly selected from the population of 233. The curve relates the weight percent nickel from x -ray fluorescence measurements to the volume percentage austenite as determined by quantitative microscopy measurements of area percent. This book provides valuable insights into the production and characterization of SRMs, which are essential for ensuring the accuracy and reliability of measurements in various fields of science and industry. Its detailed description of the methodology and results makes it a useful resource for researchers, technicians, and quality control personnel involved in the analysis of materials.
