Abstract

An alloy structure has an arbitrary shape dimension which has high uniformity in the distribution of the element composition. The alloy structure contains Fe and at least four elements, which are selected from the group consisting of elements from atomic number 13 to atomic number 79 included in Group 3 to Group 16 of the periodic table of the elements and have a ratio of the atomic radius to an Fe atom of 0.83 or more but 1.17 or less, each of Fe and the four elements is contained in an atomic concentration range of 5 at % or more but 30 at % or less, a difference in atomic concentration between at least four elements among the at least four elements and Fe is in a range of less than 3 at %, and the alloy structure has, a column crystal in which the at least four elements and Fe are solid-dissolved.
