Coexisting Crystal Structures (image)

Caption
A strong alloy made of iron, manganese, cobalt and chrome becomes ductile because it can have two coexisting crystal structures, and one structure can transform into the other. The two crystal structures can be identified by the two different colours in this cross section of the material, which was produced with the aid of electron backscatter diffraction.
