The structure of cementite - Harry Bhadeshia
The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field. A phase transformation is a change in the pattern of atoms. We work on phase transformations and the relationship between structure and properties.
