NANOPHASE materials (nc-) was first introduced by Gleiter and his coworkers, who prepared these materials using inert gas condensation technique (IGC) which were then compressed in situ by vacuum die pressing. The average grain diameters were in the range of 4-15 nm and measured by X-ray diffraction (XRD). For nc materials, the peak of XRD is broadening due to the small grain sizes and internal stresses caused by lattice deformation. In binary alloys prepared by IGC, supersaturation as well as nonequilibrium may also influence
