The Bragg edge transmission technique (BET) is a diffraction method exploiting the edges appearing in the transmitted neutron spectra crossing polycrystalline materials and is particularly suited for pulsed neutron sources. A white neutron beam passing through a sample presents, after transmission, a series of edges whose position in wavelength is directly linked to a correspondent crystalline plane distance. We plan to characterize, by exploiting BET, some pure copper and bronze standards previously thermally and mechanically treated in order to find out a direct correspondence between Bragg edges shape and action taken on the sample. We expect to be able to quantitatively describe the effect of thermal treatments and texture on the Bragg edge shape in order to set up a technique that might have large diffusion on the INES station.
