Williamson - Hall plot

  1. Dec 2, 2008 #1
    I would like to calculate the dislocation from the WH plot. I have HRXRD mesurement results with (004),(111) and (115) for omega and omega-2theta. Please someone guide me how to do?

    The williamson hall plot is rather simple to do.

    Simply plot the FWHM of your rocking curves vs Tan^2(\theta)

    Where theta is your bragg angle.




    You are also going to have to subtract out some of the information that is burried with in the FWHM. This includes:Instrument broadening,Intrinsic FWHM, Sample Curvature broadening,etc.
