Quantitative structural analysis using interference layer metallography

Microchimica Acta Aims and scope Submit manuscript

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.
