GRAIN BOUNDARY CHEMISTRY IN NICKEL BASE ALLOY 600K. STILLER
Department of Physics, Chalmers University of Technology, S-412 96 Göteborg, Sweden
The grain boundary composition of two Inconel Alloy 600 materials were investigated using secondary ion mass spectrometry and APFIM techniques. The chemical composition of materials was similar but they have received different heat treatments, Boron and carbon segregation to the grain boundaries has been observed in both materials. An enrichment of carbon was found at a twin boundary in material heat treated at a higher temperature (1024°C).
