Nanophase metals usually are many times harder but more
brittle than regular
metals. •
nanophase copper is a superhard material •
nanophase aluminum •
nanophase iron is iron with a grain size in the nanometer range. Nanocrystalline iron has a tensile strength of around 6 GPA, twice that of the best maraging steels. •
Nanophase ceramics usually are more
ductile and less brittle than regular
ceramics. == Footnotes ==
