Abstract

Nanoporous metals (NPMs) hold great promise for various applications. However, lack of understanding of NPMs' thermal response hinders their potentials in high temperature applications. In this letter, we study the thermal stability of the three-dimensional manganese-based nanoporous structure (3D-Mn-NPS) recently developed by our group using a novel laser processing-dealloying method. We determine the melting point of the 3D-Mn-NPS to be within the range of 513-593 K, significantly lower than that of the bulk alloy (1373-1473 K). We also establish the structural evolution history of the 3D-Mn-NPS under thermal processing. The nanomorphology evolves from nanowire skeletons into nanowire-nanoparticle complex and then into agglomerates of nanoparticles.
