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 ...

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 ...

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 ...
