Spark plasma sintering of alumina nanopowders produced by electrical explosion of wires
Alumina nanopowders produced by electrical explosion of wires were sintered using the spark plasma sintering technique. The results of XRD analysis show that the main phase in the compacted nanopowders is α-Al2O3. According to the SEM observations, the sintered alumina nanopowder consists of micron-sized faceted grains and nano-sized necked grains. The increase in sintering temperature resulted...
متن کاملFriction stir welding of Al-Al2O3 nanocomposite with bimodal size of alumina reinforcement produced by spark plasma sintering
Solid state joining of powder metallurgy (P/M) processed and sintered by spark plasma sintering through friction stir welding (FSW) was studied. The nanocomposites were prepared via mechanical milling followed by spark plasma sintering. The microstructural and mechanical of the joints were evaluated as a function of the different processing parameters such as rotating and advancing speeds of th...

متن کاملIncreasing of tetragonal zirconia formation in the reaction sintering of alumina-zircon
In this study it was tried to investigate on the effective parameters of the formation and increasing tetragonal zirconia phase in reaction sintering of alumina and zircon. In this way, alumina and zircon powders were mixed by the ratio of 85 to 15 wt.% and sintered at different conditions. Sintering temperature (1500-1650˚C), furnace type (conventional and microwave) and the milling time of r...
متن کاملIn-situ Fabrication of Transparent Magnesium Aluminate Spinel by Spark Plasma Sintering
Transparent polycrystalline spinel ceramic was fabricated without any sintering aids by spark plasma sintering method of a mixture of Al2O3 and MgO powders for only 10min soak at 1250°C. Densification, microstructure and optical transparency of spinel were examined. The spinel exhibits an in-line transmission of 55% for a visible-wavelength of 470nm and high hardness value of 2040 HV.
