POROUS METAL

A porous metal having a much smaller ligament size is provided. The porous metal includes a crystal of an alloy, the alloy containing n or more kinds of elements, n being an integer of 3 or more, the alloy having a composition of each element of from {(100/n)−(75/n)) at % to {(100/n)+(75/n)} at %, a...

More Information
Summary:A porous metal having a much smaller ligament size is provided. The porous metal includes a crystal of an alloy, the alloy containing n or more kinds of elements, n being an integer of 3 or more, the alloy having a composition of each element of from {(100/n)−(75/n)) at % to {(100/n)+(75/n)} at %, and the porous metal having a ligament size of 220 nm or less. The alloy is preferably a high entropy alloy or a medium entropy alloy. In addition, the alloy preferably contains a solid solution of the respective elements.
