How Temperature Brings Change in The Crystal Structure of Metals

Introduction Many materials such as iron, tin, zinc, nickel, cobalt, etc. undergo crystalline transformation in the solid state when there is a change in their temperature. They exist in one lattice form over a certain range of temperature, but at a somewhat higher or lower temperature, the lattice form changes to another lattice form, which is stable in that temperature range. Allotropy or Polymorphy An element that occurs in more than one crystallographic or lattice form is called allotropy or polymorphy, and the material in which such changes occur are known as allotropic. The process in which the crystal lattice…
