Abstract: The present disclosure relates to an SEM-EDS analysis holder device configured to fix a sample in an SEM-EDX analysis apparatus. More specifically, the present disclosure relates to an SEM-EDS analysis holder device capable of minimizing damage to a sample and reusing the sample. An object of the present disclosure is to provide an SEM-EDS analysis holder device capable of minimizing damage to a sample and reusing the sample in an SEM-EDX analysis apparatus configured by attaching an energy dispersive X-rays spectroscope (EDS) detector to scanning electron microscopy (SEM). Another object of the present disclosure is to provide an SEM-EDS analysis holder device that is easily attached or detached and includes chemical components detected by an EDS detector without a component of a holder.

Abstract: Disclosed is an entropy-controlled solid solution matrix BCC alloy having strong resistance to high-temperature neutron radiation damage. The entropy-controlled solid solution matrix BCC alloy includes three or more multicomponent main elements selected from the element group consisting of Zr, Al, Nb, Mo, Cr, V, and Ti selected based on a neutron absorption cross-sectional area and a mixing enthalpy. Each of the elements is included in an amount of 5 to 35 at %, and the entropy-controlled solid solution matrix BCC alloy is a BCC-structure solid solution matrix alloy in a medium-entropy to high-entropy state. In this invention, damage caused by neutron radiation is reduced, and entropy is controlled to thus ensure a solid solution matrix BCC structure having a slow diffusion speed, and accordingly, resistance to void swelling due to radioactive rays is high.
