Summary

The purpose of the present communication is threefold: -to demonstrate that the interphase boundary determined by Plichta and Aaronson (PA) can be shown analytically to have the lowest energy parameter P of all possible O-lattice boundaries. -to explain the significance of the calculated 0.05° rotation around [0001] and its relationship to the more general principle of an invariant line. -to show that the optimum interphase boundaries are generally quite different for coherent and semicoherent precipitates having the same Burgers orientation relationship (OR) with the matrix.
