“…Using this and other new SPS methods, it is also possible to synthetize materials with metastable phases or intermetallic alloys [ 1 , 2 , 3 , 4 ]. The HP SPS method belongs to a new generation of SPS processes, and it was already successfully employed for example for the sintering of ZrC-based composites [ 5 ]. Among these processes, pulsed electric current SPS [ 1 ], hot pressing before SPS, which involves high-temperature exposures and long-term durations [ 2 ], and self-propagating high-temperature sintering prior to SPS [ 3 ] are now well-established modern and reliable SPS techniques.…”

Ti–Al–Si alloys are prospective material for high-temperature applications. Due to low density, good mechanical properties, and oxidation resistance, these intermetallic alloys can be used in the aerospace and automobile industries. Ti–Al–Si alloys were prepared by powder metallurgy using reactive sintering, milling, and spark plasma sintering. One of the novel SPS techniques is high-pressure spark plasma sintering (HP SPS), which was tested in this work and applied to a Ti–10Al–20Si intermetallic alloy using a pressure of 6 GPa and temperatures ranging from 1318 K (1045 °C) to 1597 K (1324 °C). The low-porosity consolidated samples consist of Ti5Si3 silicides in an aluminide (TiAl) matrix. The hardness varied between 720 and 892 HV 5.

“…High pressure sintering experiments were performed using two different equipments: (i) the HP-SPS-Belt equipment at ICMCB (Bordeaux) [12] and (ii) the HP-SPS-Bridgman equipment at IAMT (Krakow) [13]. Conventional SPS experiments were done to test the influence of the pressure and pulse electric direct current on sintered compacts.…”

Ultrahigh pressure SPS processing is demonstrated with high pressure (HP) Belt and high pressure Bridgman apparatus. These HP apparatuses are capable of working in temperature range 20°C-1800°C and the pressure ranges of 800 MPa-6 GPa (HP-SPS-Belt) and 4-6 GPa (HP-SPS-Bridgman) coupled respectively with pulse electric direct current. The designed equipment can be employed for various applications in materials processing to fine tune materials properties through microstructure engineering by employing high pressure and pulse electric current. We have demonstrated the benefits of HP-SPS-Belt and HP-SPS-Bridgman in comparison to conventional SPS to obtain dense sintered compact with β-SiC as a demonstrative material at comparatively low temperatures (1300°C), duration (3 minutes) and pressure (4 GPa). The initial nanosized grains are retained in the sintered compact. The developed innovation has huge potentials for various applications for materials processing, consolidation and assembling in Materials Science.

“…High pressure plasma sintering (HP SPS) was also tested. This innovative spark plasma sintering technology is used for difficult-to-sinter materials, such as polycrystalline diamond, refractory materials, cubic boron nitride, and ceramic composites [ 133 , 134 , 135 , 136 , 137 ], and has already been used for sintering ZrC-based composites [ 138 ]. A pulsed electric current heats the material from the outside as well as inside, which guarantees good powder compaction [ 136 ].…”

“…It is performed at very high pressure (up to 8 GPa) and very short time (tens of seconds) [ 133 ]. The short sintering time (maximum 3 min) eliminates the main problem of high-temperature processes, i.e., the tendency of grain growth in sintered material with increasing temperature and time [ 138 , 139 , 140 ]. Due to the high pressure, the process can also be applied to intermetallic compounds or minerals [ 141 ].…”

This paper describes the effect of silicon on the manufacturing process, structure, phase composition, and selected properties of titanium aluminide alloys. The experimental generation of TiAl–Si alloys is composed of titanium aluminide (TiAl, Ti3Al or TiAl3) matrix reinforced by hard and heat-resistant titanium silicides (especially Ti5Si3). The alloys are characterized by wear resistance comparable with tool steels, high hardness, and very good resistance to oxidation at high temperatures (up to 1000 °C), but also low room-temperature ductility, as is typical also for other intermetallic materials. These alloys had been successfully prepared by the means of powder metallurgical routes and melting metallurgy methods.
