“…The first recess (1.7 mm) corresponds rather to the compaction of the powder. As in previous works [5][6][7][8], this displacement is probably attributed to the re-arrangement of the initial powder particles under the sole effect of the applied pressure since the temperature is still too low to induce any phase transformation. Between 600 and 1060 ℃ , the displacement increases to 2.…”

“…The present work is a continuation of our previous studies [5][6][7][8]. The main purpose of this work is to study the influence of the grain size of the starting mixture by using the same starting mixture Ti/SiC as in our previous work [7], but which differs by the microstructure of silicon carbide.…”

“…In this context, our group has used several starting mixtures to elaborate Ti 3 SiC 2 . Among these mixtures, we quote Ti/Si/C [5], Ti/C/SiC [6], Ti/SiC [7], and Si/TiC [8]. Several researchers reported on the synthesis of Ti 3 SiC 2 starting from Ti/SiC in fine powder or nonpowder forms such as films, foils, and rods by using different processes [9][10][11][12][13][14].…”

In this paper, the synthesis of Ti 3 SiC 2 from SiC/Ti powder using reactive spark plasma sintering (R-SPS) in the temperature range of 1300-1400 ℃ is reported. The results show that the purity of Ti 3 SiC 2 is improved up to 75 wt% when the holding time is increased from 10 to 20 min at 1400 ℃. The thermodynamic and experimental results indicate that Ti 3 SiC 2 formation takes place via the reaction of a pre-formed TiC phase with the silicides, formed from the eutectic compositions. Detailed analysis of mechanical behaviour indicates that samples with higher percentage of secondary phases exhibit higher microhardness and better resistance compared to the near single phase Ti 3 SiC 2 .

“…Besides these advantages, several recent works have shown that SPS can also be used as a reactive process to elaborate nanostructured or submicrometer grain-sized materials starting from raw reactants [2][3][4][5]. In this process, called reactive SPS (R-SPS), synthesis and densification are achieved in a single step.…”

In this study, submicrometer grain-sized metal matrix composites (MMCs) based on nickel were elaborated via a bottom-up strategy combining the polyol process and a non-conventional heat treatment route. First, four sets of nano-sized Ni–P metastable alloy nanopowders with an average particle size centered at 50, 100, 130, and 220 nm were prepared by the polyol process modified by the addition of hypophosphite (strong reducing agent) and heterogeneous nucleation using silver nitrate and platinum salt (nucleating agents). The heat treatment step was realized by reactive spark plasma sintering (R-SPS) at identical heat treatment conditions (600 °C, 53 MPa, and 10 min as holding time). R-SPS transformed the Ni–P metastable alloys into bulk submicrometer grain-sized MMCs with Ni as the matrix and Ni3P as the reinforcement. Mechanical and magnetic properties of the four MMC samples were found to be closely related to the grain size of the Ni matrix, which varied from 247 to 638 nm. Yield stress, maximum stress, and coercive field increased when the grain size decreased, while plastic strain and magnetization saturation decreased. The reinforcement Ni3P phase enhanced the mechanical characteristics of the composite. Crossover behavior was observed at around 350 nm Ni grain size, where a ductile and soft magnetic composite was tuned into a hard mechanical and semi-hard magnetic one.

“…However, their extensive application is limited due to their poor toughness [1,2,3]. To improve the strength and toughness of SiC ceramics, processing techniques, such as chemical vapor infiltration (CVI), liquid polymer infiltration, reactive melt infiltration (RMI), and spark plasma sintering (SPS), were applied [4,5,6]. Among these methods, RMI, which is most suitable for realizing the net shape of SiC matrix composites at low cost, was found to satisfy the above requirements [7].…”

This paper proposes a simple reactive melt infiltration process to improve the mechanical properties of silicon carbide (SiC) ceramics. SiC matrix composites were infiltrated by Al–Si (10 wt.%)–xTi melts at 900 °C for 4 h. The effects of Ti addition on the microstructure and mechanical properties of the composites were investigated. The results showed that the three-point bending strength, fracture toughness (by single-edge notched beam test), and fracture toughness (by Vickers indentation method) of the SiC ceramics increased most by 34.3%, 48.5%, and 128.5%, respectively, following an infiltration with the Al–Si (10 wt.%)–Ti (15 wt.%) melt. A distinct white reaction layer mainly containing a Ti3Si(Al)C2 phase was formed on the surface of the composites infiltrated by Al alloys containing Ti. Ti–Al intermetallic compounds were scattered in the inner regions of the composites. With the increase in the Ti content (from 0 to 15 wt.%) in the Al alloy, the relative contents of Ti3Si(Al)C2 and Ti–Al intermetallic compounds increased. Compared with the fabricated composite infiltrated by an Al alloy without Ti, the fabricated composites infiltrated by Al alloys containing Ti showed improved overall mechanical properties owing to formation of higher relative content Ti3Si(Al)C2 phase and small amounts of Ti–Al intermetallic compounds.
