Dear Rietveld users, This is very simple question, even though, please help me,
I get a Williamson - Hall plot in the Fullprof (winplotr window) using my instrumental resolution file (IRF =4), after the linear fit I got the values of equation y = ax + b a = 0.01841 b = 0.95438 chi2 = 0.327242 I calculated size from the intercept such as (1/b * 1000) = (1 / 0.95438) * 1000 = 1047.80 angstroms How can I calculate the strain, please explain, with best regards SM
