Heterogeneous composite material and method for producing the same

A heterogeneous composite material and a method for manufacturing the heterogeneous composite material are provided. The heterogeneous composite material includes a first compression structure formed by compressing a first material, and a second compression structure formed by compressing a second material different from the first material, and disposed in close contact with the first compression structure, wherein at least a portion of the first compression structure and at least a portion of the second compression structure are disposed on both sides of a boundary surface existing in a circular shape with a predetermined radius with respect to a central axis in a state in contact with each other at the boundary surface. 本发明提供了异质复合物及异质复合物的制造方法。异质复合物包括：第一压缩结构体，其通过压缩第一材料来形成；第二压缩结构体，其通过压缩与第一材料不同的第二材料形成，并且与第一压缩结构体紧贴地布置，其中，第一压缩结构体的至少一部分与第二压缩结构体的至少一部分以在以中心轴为基准具有恒定半径的圆形界面彼此接触的状态布置在界面的两侧。
