Special Issue Information

Dear Colleagues,

Field-assisted sintering techniques include field assisted sintering/spark plasma sintering, flash sintering, microwave sintering, discharge sintering, and other technologies where electric or magnetic fields drastically enhance the sintering kinetics. These technologies have been intensively investigated over the last decades. Now, many of them are in transition from laboratories to industrial applications. Despite a number of excellent research papers, reviews, and books are newly published, the development is so fast, that a new look into the actual results is needed. The aim of this Special Issue is to update the achievements, open a discussion about the appearing problems, and present examples of the upscaling and industrial applications of field-assisted sintering technologies. Papers on physics, chemistry, technology, industrial application, and equipment for the realization of these technologies are welcome. We are particularly interested in small or large reviews in special topics such as the mechanisms and modeling of field-assisted sintering, field-assisted sintering of oxide ceramics, reactive field-assisted sintering, and so on. We also encourage the submission of papers on the application of field-assisted sintering in industry, including the sintering of parts with a complex shape, and on progress in the design of related equipment. Manuscripts from both the academic community and from industry are welcome.

The thermal and oxidation resistance of elements found in the combustion boilers of power generation plants are some of the most important factors deciding their effectiveness. This paper shows the experimental results of the influence of NiCr-based material composition on the microstructure and phase changes occurring during the oxidation and corrosion process. NiCr alloy was modified by the addition of rhenium and aluminum oxide. Materials were densified using the spark plasma sintering method at a sintering temperature of 1050 °C. Oxidation tests conducted up to 1100 °C under synthetic airflow revealed the formation of a thin Cr2O3 layer protecting the material against in-depth oxidation. Results of electrochemical corrosion in a 0.5 M NaCl solution indicated a positive role of Re and Al2O3 addition, confirmed by low corrosion current density values in comparison to the other reference materials. According to the provided positive preliminary test results, we can conclude that a NiCr-Re-Al2O3 system in coating form was successfully obtained by the plasma spraying method. Full article

Abstract: The paper presents the results of investigations on the influence of sintering temperature in the range of 900–1000°C on the microstructure and selected properties of composites on an M3/2 high speed steel matrix with a 50 wt% addition of iron produced by spark plasma sintering. M3/2 high speed steel powder and NC 100.24 iron powder were mixed in a Turbula T2F shaker/mixer. The prepared powder mixtures were sintered using an HP D 25–3 furnace. As a result of SPS, M3/2–Fe composites were obtained. The microstructure of these composites includes both iron grains and high speed steel grains with characteristic precipitates of MC and M6C carbides. Based on the performed density measurements, it was shown that the relative density of the obtained composites is from 92 to 98% and grows with increasing the sintering temperature. Also, it was shown that the relative hardness and bending strength depend on the relative density. Together with the rise in the relative density from 92 to 98%, increases in the hardness from 237 to 367 HBW 2.5/187.5, and the bending strength from 956 to 1107 MPa were obtained. The M3/2–Fe composite obtained at the temperature of 1000°C is characterized by the best density–hardness–bending strength relation, which amounts to a relative density of 98%, the hardness of 367 HB 2.5/187.5, and bending strength of 1107 MPa.
