TopicCompaction of zirconium powders by high voltage electric discharge consolidation and spark plasma sintering
This work presents the results on the comparison of two sintering techniques: HVEDC and SPS. Features of the consolidation processes of zirconium alloy powders with particles of various shapes have been identified. The average particle size of the powder was 250 µm. The optimal processing modes enabling the fabrication of high-density samples have been determined. The mechanical properties of samples have been measured by Vickers hardness test. A comparison of the results had been discussed according to data of mechanical tests and microstructure investigations.
