Porous metals

Among porous metals, nanoporous gold—a bi-continuous structure composed of ligaments and pores—is highly attracting attention in functional materials owing to its high specific surface area and chemical inertness of gold.

We are working on enhancing the mechanical reliability of porous metals by better understanding the fundamental mechanisms of mechanical behavior.
For this purpose, we perform several types of mehcanical testing—tension, compression, nanoindentation, bending, and creep—with porous metals having variously controlled microstructures.

Ultimately, understanding the mechanical behavior of porous structures links to developing a structural materials for high-strength and lightweight applications.
