Summary
This presentation describes the possibilities, but also the limitations and errors, of the quantitative structural analysis of metallic multi-phase systems by means of interference layer metallography. The following aspects are considered in detail:
-
-effect of interfering layers,
-
-structural development by gas ion etching and evaporation coatings,
-
-application of quantitative structural analysis with the example of a high-temperature metallic alloy,
-
-determination of the optical constants of all phases involved in the structure and the coating materials,
-
-criteria for selecting coating materials; possibilities of preselecting the thickness of the interference layer and the wavelength of the monochromatic observation light,
-
-sources of error and limitations of the colour-contrast method.
