This table exhibits the remarkable fact that cast iron is harder than all the other metals; it was found to be harder than any alloy. Its great resistance to a crushing force—on account of its c ...

Scientists have developed a new alloy composed of multiple metals that exhibits nearly zero thermal expansion across an ...

The ‘new’ material could be of great use in fields in which extreme temperature changes are common or precise measuring ...

Invar, for example, an alloy of iron and nickel, is known for its extremely low thermal expansion. How this property can be explained physically, however, was not entirely clear until now.

The compound of iron and aluminum with the chemical formula ... In the most well-known superelastic material, i.e. TiNi alloys,which consist of precious and rare metals of titanium and nickel ...

Iron is the main ingredient in various forms ... It is the principle strengthening element in carbon steels and low-alloy steels. Atomic number 6, atomic weight 12.01115. Manganese (Mn ...

Breakthrough in materials research: an alloy of several metals has been developed that shows practically no thermal expansion ...

IT is generally accepted that the lattice parameter of retained austenite in quenched iron—carbon alloys increases continuously and linearly with the increase of carbon content. So far ...

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 ...
