Sintering and Properties of W-25% Re Composition for Sermet Fuel Production by Spark Plasma Method
In this study, the sintering of tungsten metal powders of 99.99% purity and 7.8 µm for cermet production by Spark Plasma Sintering (SPS) method at temperatures between 1300°C and 1700°C for 5 minutes, 10 minutes, 20 minutes and 30 minutes was investigated. The relative densities of the sintered tung...

| description | In this study, the sintering of tungsten metal powders of 99.99% purity and 7.8 µm for cermet production by Spark Plasma Sintering (SPS) method at temperatures between 1300°C and 1700°C for 5 minutes, 10 minutes, 20 minutes and 30 minutes was investigated. The relative densities of the sintered tungsten samples were found to have relative densities ranging from 83% to 94% of the theoretical density of tungsten. Micro hardness (Vickers) test, 94% relative density of the sample was found to be 298 kg / mm2 hardness. In order to improve the mechanical properties of cermet material, 99.99% purity and 13.3 µm dimensions of Rhenium powders and 99.99% purity and 0.5 µm sizes of Tungsten powders, 75% by weight Tungsten-25% Rhenium powders are -
mixed using high-speed mills. It was found that the powders prepared in high speed ball mill showed less displacement (3%) under the same temperature and pressure. W-25% Re powders were sintered with SPS method at different temperatures and temperatures of 1700oC and 1900°C. The highest relative density at 1700°C was 97.6%. In contrast, the minimum displacement (3.3%) was obtained from the sintered sample for 40 minutes at 1900 °C. In the light of these results; It has been determined that SPS method can be used in series production of tungsten-rhenium alloys for cermet fuel production. |
