AI Article Synopsis
- The paper discusses a new method for creating pure rare-earth-metal bulks with controlled nanostructures using an 'oxygen-free' in situ synthesis technique that combines inert-gas condensation and spark plasma sintering (SPS).
- This method allows for the production of rare-earth bulks with various structures, including amorphous and nanocrystalline forms.
- The resulting nanostructured materials show significantly enhanced physical and mechanical properties compared to traditional polycrystalline bulks, facilitating better research into metallic materials sensitive to air exposure.
Article Abstract
The preparation and characterization of pure rare-earth-metal bulks with controllable nanostructures are reported in this paper. A novel 'oxygen-free' in situ synthesis technique that combines inert-gas condensation with spark plasma sintering (SPS) technology is proposed. Taking into account the special mechanisms of SPS consolidation and the scale effects of nanoparticles, we introduced practical procedures for preparing rare-earth bulks of amorphous, mixed amorphous and nanocrystals, and nanocrystalline microstructures, respectively. Compared with the conventional polycrystalline bulk, these nanostructured bulks exhibit substantially improved physical and mechanical properties. This technique enables comprehensive studies on the microstructures and properties of a large variety of nanostructured metallic materials that are highly reactive in the air.
