Alloy banding / Carbide segregation

Very interesting discussion.
Wether or not these banding affects the cutting ability or edge holding to any noticeable effect, their appeareance as blade steel is amazingly beautiful, so worth pursuing.
 
OT, Stefano, what did you do in the "old days" on the island ? Was there any source of iron or was it imported from the mainland ? How difficult is it to get blade steels to you now ?
 
I too found these patterns as candies for the eyes. As-shown level/severity of structure heterogeneous, I don't think it cutting performance degrade much (not noticeable). However impact/chopping performance would be much lower.

Our island is full of iron ore, i have a full bin of magnetite i collected, just in case some day i'll get the itch for smelting. I'll think of it when i'd get a real press or a powerhammer ;)
 
Most of the 1084 I've used gets a wootzlike pattern in the unhardened section as well-often very fine, but fascinating nonetheless
 
Hitachi Blue #2 with incredible banding.

I agree. It looks almost like wootz steel. I only have enough for 2 or three more knives though.
 
This one doesn't go away with normalizing or forging temps. I think it's the top center of the pour from the mill.
 
What's this about?

1095. Don't remember doing anything out of the ordinary with the heat treat.
 
Haha. I'd duplicate it if I could. It's cool as heck.
