HCP silicon-rich k phase and the FCC copper-rich α-matrix in Cu-Si alloys forms ___

HCP silicon-rich k phase and the FCC copper-rich α-matrix in Cu-Si alloys forms ___ Correct Answer A semi coherent interface

Here it forms a fully coherent interface. This requires the two crystals to be oriented relative to each other in a special way such that the interfacial plane has the same atomic configuration in both phases, disregarding chemical species.
