1. A heterogeneous composite material comprising:
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 that has a predetermined radius with respect to a central axis and exists in a circular shape in a state in contact with each other at the boundary surface,
wherein the boundary surface includes a plurality of detailed boundary surfaces having different radii with respect to the central axis,
wherein a first portion of the first compression structure and a first portion of the second compression structure are disposed on both sides of the first detailed boundary surface in a state in contact with each other at the first detailed boundary surface among the plurality of detailed boundary surfaces, and
wherein a second portion of the first compression structure and a second portion of the second compression structure are disposed on both sides of a second detailed boundary surface in a state in contact with each other at the second detailed boundary surface among the plurality of detailed boundary surfaces.
