Fig. 4: Schematic illustrations of the fabrication of ultrafine nanoporous μ-Co7Mo6 intermetallic compound by LMD.
The process involves dealloying, to create a nanoporous structure of an ordered intermetallic phase, and subsequent thermal coarsening, to increase the feature size of the porous structure. Ed represents the energy barrier of dealloying to form the nanoporous intermetallic compound. Ecr, and Eci represent energy barriers of thermal coarsening for random solid-solution alloys and intermetallic compounds, respectively. The green, orange, yellow and while balls represent the Co, Mo, Ni, and dissolved Ni atoms, respectively.
