Grain Boundary Phase Transformations

  • Edward W. Hart


Metals and alloys are commonly employed and processed in the form of polycrystalline aggregates. The mechanical strength of such aggregates depends greatly on the strength of the interfaces or grain boundaries that join the individual crystal grains. In general a grain boundary can be expected to be weaker than the grain matrix since the degree of atomic order in the boundary is lower than that in the crystal. Furthermore, the chemical composition with respect to solute components and the diffusive properties of a grain boundary differ from the crystalline matrix.
