delta iron


delta iron
when pure or practically carbon-free iron is cooled from above its melting point it solidifies at about 1535 deg C as delta iron having a body-centered cubic lattice structure, which persists down to about 1400 deg C. On further cooling it undergoes an allotropic change to gamma iron which has a face-centered cubic lattice and is non-magnetic.
