Scientists surmise that if iron is not combining with other particles, it might be forming pure metal which is invisible in outer space. That theory now appears unlikely, according to a paper ...

Pure iron can have two different crystal structures as its temperature is increased from ... In going through the eutectoid reaction temperature, carbon is displaced from the metal lattice to form the ...

Metals are the only substances that are magnetic. But some metals are magnetic and some are not. The most common magnetic metal is iron. You don't see too many objects made of pure iron but you do see ...

The alloy is harder and stronger than the pure metal. Steel contains atoms of other elements as well as iron. These atoms have different sizes to iron atoms, so they distort the layers of atoms in ...

Smelting to retrieve the pure iron metal from these sources would have revealed their magnetic attraction. So, the phenomenon has probably been known for some 3,000 years. Like the discovery of ...
