- Abstract
- A self-organized superlattice containing modulated layers in Cu5Zr was manufactured by casting a Cu-Zr system. Substitutional Zr atoms caused compressive stress in the superlattice so that periodic stress fields were formed with a long-range order along the (110) directions on {111} for stress relaxation. On the other hand, it was demonstrated theoretically by atomistic simulations that a superlattice could form easily due to the large negative enthalpy of formation in the structure (-12.890 kJ/mol of atoms).
