Results and Discussion
The XRD patterns of the elemental powder mixture with a composition Ti50Cu28Ni15Sn7 after
milling for 8h are shown in Fig. 1 (a).
In the case of the composite powders, as seen in Figs. 1(b), no diffraction peaks of crystalline CNT can be detected in the XRD patterns for the composite powders of Ti50Cu28Ni15Sn7 alloy mixed with 4 vol. % CNT after 8h of milling.
Though not shown here, consolidated BMG Ti50Cu28Ni15Sn7 and composite samples exhibited similar XRD and DSC results as those of the corresponding powders shown in Figs. 1 (XRD) and 2 (DSC).

In history, people expounded and proved the rationalization of the existence of them [1-3], worked out the specific configurations of them basing on the principle of minimum free energy and the Curie principle in various cases [1-5], and investigated the dynamics of the movements of domains and domain walls (especially the domain switch) [6-9].
As is known that the equilibrium thermodynamics is strictly tenable only on condition of the thermodynamic limit (1) where is the number of particles and the volume of system, respectively.
