Some solid metals exist in various structural forms, a phenomenon known as polymorphism. Iron, for example, adopts one type of cubic lattice (α-iron) at room temperature, but transforms into another ...

The toughness, ductility, and wear resistance of metallic alloys are dictated by the phases present in their microstructure and how these phases are distributed. During heat treatments such as ...

Scientists have used pressure with a twisting shear to permanently deform silicon, an important material for electronics. The resulting changes in silicon's microstructure produce material phases that ...

A team of researchers has reviewed a unique method for reforming the structures of ultra-small nanomaterials. These nanomaterials, called metal nanoclusters, bridge the gap between the metal atom and ...

ITHACA, N.Y. -- Just as a snowflake’s intricate structure vanishes when it melts and transforms when it refreezes, the microstructure of metals can change during the 3D printing process, resulting in ...
