Bazaleev M. Development of physical and technological bases of thermographic control аnd monitoring of state of materials for estimation of resource of nuclear power engineering equipment and facilities by using infrared thermography methods

Thesis covers the problem of crack detection in materials and estimation of nuclear facilities states by using infrared (IR) thermography methods, which allow one to use non-destructive methods of thermal control using thermal imaging technology more efficiently. A fundamentally new approach to the strategy of thermographic monitoring of industrial facilities that presupposes the use of cyclic energy and energy of thermoelastic stresses generated by technological equipment, as sources of an activation of thermal developments of structural inhomogeneities and defects in materials has been developed. The original set of bench equipment and techniques for thermographic studies of defect structures by using both separate and simultaneous activation of the samples by thermal, acoustic (cyclic stress) and electromagnetic fields has been created. Studies of the features the formation of the highly informative IR radiation field that reflects the spatial and temporal thermal developments of defect formation structures have carried out.
