The article gives an insight into the progress in metallography over the la
st 22 years. The testing of new metallographic preparation and investigatio
n instruments stands in the foreground; therefore the Ultrafrase, Accutom,
electrolytic preparation and laser scanning microscopy are mentioned. Metal
lographic investigations of diffusion welded metal/ceramic and glass/glass
composites and the organisation and execution of round-robin tests for the
preparation of metals, ceramics, semiconductors and material composites are
described.
