Diamonoid Stabilized Fine-Grained Metals


技術優勢

Readily produced fine grained and nanocrysatilline metals and alloys of greater high temperature strength and stability.


詳細技術說明

A common method for strengthening metals without large decreases in ductility is to reduce the grain size of the metal. However, this strategy does not generally lead to improved strength at elevated temperatures because the grains grow larger by diffusion and grain boundary sliding can occur. This invention adds diamonoids to aluminum resulting in a marked grain size stability at elevated temperatures making it possible to retain the high strength of fine grained metals without sacrificing ductility.
