Modern Evaluation of those weapons has shown that these components supported the catalytic development of carbon nanotubes, which consequently promoted the development of cementite (Fe3C) nanowires. The malleability in the carbon nanotubes offset the brittle mother nature of your cementite, and endowed the ensuing metal with a unique mix of strength and suppleness. Expertise in how to produce what came to identified as Damascus metal died out during the eighteenth century probably on account of exhausting ore resources with the ideal combination of impurities.
