Аннотация

Scanning electron microscopy, different methods of electron diffraction, x-ray spectrum microanalysis and x-ray diffraction analysis are used to study the microstructure and crystallography of eutectic chromium carbides in HP40NbTi alloys in as-cast condition and after endurance tests for 2 – 100 h at 1150°C. The morphology and the transformations of the carbides after the high-temperature endurance tests are investigated.
