Özet
The key characteristic of ball-milled powders consolidation process is to achieve densification and particle bonding without degradation in mechanical properties. Recent demonstrations of novel processing methods involving temperature, high shear and high pressure have shown promise for bonding high strength particulate materials. In this study, we report the ability of multi-pass high temperature equal channel angular extrusion (ECAE) and hot pressing to produce fully dense and well-bonded bulk Ferritic alloys from nanocrystalline Fe-Ni-Zr powders. Subsequent microstructural characterizations indicate full consolidation via hot extrusion with grain growth to micron sizes. The consolidated alloys demonstrate an extremely high strength (4-6 GPa) at room temperature.
