Alloy Steels with Carbon Nanotubes Directly?

[St33L]

I'm curious... if you took some of the 3rd gen PM metals still in powder form at its earliest stage of manufacture, and added in carbon nanotubes and replace the carbon content, would the geometry and size of the carbon nanotube substitute make the steel better?

Any thoughts, scientific studies, actual experiments, etc? I know that some knife makers have coated knives with carbon nanotubes, but I'm specifically inquiring about steels that have carbon nanotubes directly alloyed with them.

Thanks in advance!

I don't know if a bunch of nanotubes are likely to survive forging or not. I don't think that sort of testing is happening yet. Nanotubes are too useful structurally to use them to reinforce something as crude as a cutting blade.

However, I remember reading an analysis a few years ago that suggested that nanotubes or similar structures were found naturally in some samples of Wootz steel.

Unfortunately "nano" is a magic word these days .I've become suspecious of any claim about it . It's become difficult to get research funding without nano appearing on the request !
But metallurgical advancements are seen all the time, we may get some interesting blades soon !
