Method for determining uniformity and method for measuring density from amorphous metal using ultra small angle neutron scattering

Using a neutron micro each scattering according to one embodiment of the invention a method of measuring the uniformity and density from the rough surface of the amorphous metal is prepared in a mixed solvent comprising two or more liquids to prepare the amorphous metal material, and mixing adjusting the concentration ratio of two or more liquids contained in the mixed solvent is measuring the scattered intensity of the solvent, the scattering intensity of the scattering intensity to the sample in measuring the scattered intensity of the sample, a mixed solvent so as to have the same value, and amorphous and a step of determining the uniformity of the metal material.
