Would you tell me how to measure the stacking fault energy of face-centered cubic structured metals and alloys by experiment? Especially, I would like not to use a transmission electron microscope. The simplest method possible is preferable.
Dear Yuhi Mori,
X-Ray Diffraction along with Rietveld refinement technique could be used to find the SFE of metals. This has already been reported in the case of Cu.

Hi
Indeed، one can determine the width of the SF by X-Ray Diffraction.Subdequently ,one can measure the SFE from the width of the SF. The higher the SFE the smaller the width of the SF the easier for the SF to slip .ln contrast,the lower the SFE the bigger the width of the SF the harder for the SF to glide.
Yes I agree with Dr. Habib and Dr. Anas.. XRD is useful for this purpose
