Cold Consolidation of Metal-Ceramic Nanocomposite Powders with Large Ceramic Fractions
Josep Nogués, leader of the Magnetic Nanostructures group at CIN2 (ICN-CSIC), together with other researchers, published the paper 'Cold Consolidation of Metal-Ceramic Nanocomposite Powders with Large Ceramic Fractions' on Advanced Functional MaterialsVolume 18 Issue 20, Pages 3293 - 3298.
Co/-Al2O3 powder mixtures (5, 10, 20, 30, 40, and 50 mass % of -Al2O3) have been ball-milled and, subsequently, consolidated at room temperature by means of a high pressure torsion procedure in order to produce bulk nanostructured composites. For mixtures up to 20% of -Al2O3, the cold-compaction results in roughly fully dense disks with relatively high microhardness values. However, the compaction for 30, 40, and 50% of -Al2O3 is less effective, resulting in a reduction of the microhardness although a structure in the nanoscale range is still preserved. A detailed structural investigation has been also performed.
