Needles inside the ferrite in carbon steel
Needles inside the ferrite in carbon steel
(OP)
Just to share this characterization of a piece of carbon steel with a surface finish, in which needles were precipitated inside the ferrite near the surface.
I am in the process of analyzing them in SEM to identify their qualitative composition.
Have you characterized any like that?

By 'surface finish' do you mean a coating or surface modification?

An article by Vander Voort shows similar ones that result from nitriding.
Anyway EDS could be useful (or not, it does not matter, it's in process).

(needles yes are precipitates: in theory Iron nitrides)
now i will analyze if they are inocuos or not for a good perfomance of the component.
