| Abstract Scope |
Nanoporous tungsten is of great scientific interest, as it combines the beneficial properties of tungsten with the positive attributes of nanoporous foams and has a great potential to satisfy the need for high performance materials that can endure harsh environments. In this work, nanoporous tungsten, characterized by a continuous network of nanocrystalline tungsten ligaments and nanopores, was created on a bulk scale through a unique technique route involving the severe plastic deformation followed by the selective phase dissolution. The mechanical properties, which are an important consideration during many practical applications, were investigated by employing depth-sensing nanoindentation and other small-scale testing in situ in the scanning electron microscopy. Based on this, the elemental plasticity mechanisms governing the mechanical behavior were elucidated. The promising mechanical results of the created nanoporous tungsten will serve as a foundation for forthcoming related scientific studies and engineering applications. |
