Strain Diffractometer (TKSN-400)

TKSN 400 is a high resolution two-axis diffractometer optimized for investigation of internal stresses in polycrystalline materials. Due to its equipment, the instrument is dedicated especially for thermo-mechanical testing of materials, i.e. to study the deformation and transformation mechanisms of modern types of newly developed materials. Neutron diffraction performed in situ upon external loads, brings a wide range of valuable structural and sub-structural parameters of the studied material which is easy to correlate with parameters of external loads.
