Time-dependent properties of the speckled intensity patterns created by scattering coherent radiation from materials undergoing spinodal decomposition are investigated by numerical integration of the Cahn-Hilliard-Cook equation. For binary systems which obey a local conservation law, the characteristic domain size is known to grow in time tau as R=[Btau](n) with n=1/3, where B is a constant. Th...

Fe–Cr–Co alloys are becoming important as half-hard magnet which can be subjected to plastic deformation process for their novel applications including non-contact electromagnetic brake because of its large hysteresis loss. Its magnetic hardness depends on the modulated structure formed by spinodal decomposition. It is clarify effect decomposition optimizing heat treatment after process. In pre...

Spinodal decomposition is an important mechanism of exsolution. However, spinodal has not been observed in natural sulfide intergrowths. We utilized focused ion beam (FIB) and transmission electron microscopy (TEM) techniques to confirm intergrowths (chalcopyrite bornite). According FIB TEM analyses, occurred as small curving alternating dark bright fluctuations bornite–chalcopyrite Due the low...

Abstract The stability of thin liquid films on a surface depends the excess free energy system involving various short‐range and long‐range interactions. When forced to wet an unfavorable surface, dewet into multiple small‐sized droplets via spinodal, homogeneous, or heterogeneous nucleation process. However, if total can be manipulated using external stimuli, for example, electric field, tempe...
