Composite alloy having a three-dimensional periodic hierarchical structure and method of producing the same
A composite alloy has a three-dimensional periodic hierarchical structure having hard and soft metallic phases periodically arranged with a period having a length ranging from a nanometer scale to a millimeter scale. It is preferable that the three-dimensional periodic hierarchical structure has an alloy composition sloped microscopically within the period. The three-dimensional periodic hierarchical structure may be formed by periodically arranging rod-like hard and soft metallic phases having a width and a thickness ranging from a nanometer scale to a millimeter scale so that their side surfaces are adjacent to one another.
