Metallrand
Metallrand is a term used in materials science to describe a thin, continuous metallic rim that forms at boundaries within certain metallic materials during high-temperature processing or rapid solidification. The name derives from the German word for “metal edge.”
Formation and characteristics: Metallrand arises from diffusion and segregation of alloying elements at interfaces, leading to
Occurrence and materials: Metallrand has been reported in a variety of alloys subjected to high-temperature processing,
Significance and study: Research on metallrand uses electron microscopy and compositional analysis to understand its impact
