I understand Alan, and I have not read Prof Piaskowski's work.

My question is regarding the iron-nickel alloys in the meteorite material (my apology for not beening clear).

In Iron Meteorites, there are two major alloys of iron-nickel:

Kamacite: a solid solution of around 7.5% nickel.
Taenite: a solid solution of more than 25 percent nickel.

There are also the possibilities of having Iron Carbides - solid solutions of Fe, Ni & Co with Carbon, such as Cohenite and Haxonite. But let us ignore those for the moment. If I recall, iron and nickel are always alloyed together unless in oxide or silicate form – in meteorites.

My question was, what happens to these concentrations of iron-nickel on forging and folding? Do they leave a pattern that would be pamor like? Or do they simply mix and are indistinguishable (in the iron and meteorite mix- if you were to make a blade from this material alone)?
