Photometric Analysis of Structure-Strength Properties Relationships

The modern technologies of mechanical and heat treatment of metals and alloys are based on understanding of organic relationship between the physicomechanical properties of materials and their structural state. It is difficult to express the mechanical properties of materials in the form of contribution of individual structural constituents due to complexity of simultaneous evaluation of all parameters of the structural state of a material and its mechanical properties. Therefore, the methods of description of structural state deserve attention based on generalized parameters expressed in terms of sets of variables describing the influence of various structural defects. This work discusses the application of a parameter, which is based on photometric measurements of the spectral properties of the brightness of visible light reflection from the surface of the object to be analyzed under in situ experiment conditions during its mechanical testing, as a generalized parameter of structural state. The results of experimental verification of this approach are exemplified by 30KhGSA steel.
