Assessment of the unstressed lattice parameters for residual stresses determination by neutron diffraction in engineering materials

Popis výsledku v původním jazyce

Thermal neutrons are very useful probe in a nondestructive determination of internal stress, due to their high penetration into most materials. In comparison with conventional Xray techniques, real bulk information on both macro- and micro-strains in materials can be obtained by neutron diffraction techniques. Knowledge of the spatial and directional distribution of internal residual stresses is increasingly considered fundamental to determine their influence on properties of engineering materials and aconsequent material behaviour. As the assesment of stresses is always related to the stress free material state, an accurate evaluation of the unstressed lattice parameters, in order to determine RS by ND is one of the key tasks. It helps to avoid inacceptable errors in the course of the real material strain and stress evaluation. The availability of carefully measured zero-strain standards is also essential to confirm the absence of systematic instrumental effects determining the diffr
