Hi,
Assuming average CoKa wavelength of 1.7902 angstrom, using the values in the Table 1 of E975-22, below R values can be used: Alpha Fe: R 110 149.64 200 19.555 211 40.257 220 18.233 Gamma Fe: R 111 111.275 200 48.980 220 25.906 311 12.187 -- Dr. Xiaodong (Tony) Wang Senior Research Infrastructure Specialist (XRD) Central Analytical Research Facility (CARF) | Queensland University of Technology Address: Level 6, P Block, Gardens Point campus, 2 George St Brisbane QLD 4000 Tel: +61 7 3138 1904 | Mob: 0452 571 680 Email: [email protected] | Web: www.qut.edu.au/ife/carf At 2026-03-10 02:32:55, "Nelson Duarte" <[email protected]> wrote: Dear colleagues, I am trying to calculate the retained austenite content according to ASTM E975 using cobalt radiation. Does anyone have calculated the theoretical intensity values of the main ferrite and austenite peaks using cobalt radiation? Thank you in advance. Best regards, Nelson
