Is it possible to determine the small amount of lighter elements (with location) present in ferrite matrix by XRD or TEM or SEM-EBSD etc?

Lighter alloying elements like N and C are present (or added) in the ferrite matrix at various locations like at interstitial voids, dislocations and also at the interfaces and GB. Is there a...

Why the Fe powder heated at high temperature stick together (sintered) and form a solid mass?

I tried to heat (oxidise) the Fe powder at 500C and it got sintered (bonded) together. The bonding is so strong that its not easy to manually grind it to get back the iron oxide powder. XRD shows...
