A compound, Fe 3 C with the fixed composition Fe-6.7 wt % C bounds one end of this diagram and pure iron the other end. Pure iron can have two different crystal structures as its temperature is ...

1927), that quenched carbon steels contain a phase with a tetragonal crystal structure, which might be considered as a deformation of the body-centred cubic structure of α-iron. This has been ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

first performed X-ray diffraction measurements at high pressure and high temperature corresponding to the condition at the center of the Earth and determined the crystal structure of iron in Earth ...

In fact, the only thing needed to make them is iron and nitrogen, plus an understanding of crystal structure and some engineering ingenuity. To start things off, what even is a permanent magnet?
