A coherent nucleus with a negative misfit can reduce the critical volume free energy by forming a region of _________

A coherent nucleus with a negative misfit can reduce the critical volume free energy by forming a region of _________ Correct Answer Compressive strain

This directly implies that the smaller volume than the matrix can reduce its ΔG* by forming a region of compressive strain above an edge dislocation, whereas if the misfit is positive it is energetically favourable for it to form below the dislocation.
