“…Better interface structures were expected in the composites synthesized via this route. TiC–Ti 3 SiC 2 composites 73,74 were synthesized with an in situ reactive PDS process, by using the starting reactants of Ti, Si, and TiC powders. Figure 12 shows the XRD patterns of the representative TiC–Ti 3 SiC 2 composites, with the Ti 3 SiC 2 volume fraction ranging from 10–80%, PDSed at 1400°C.…”

As an invited paper with the designated title to this focused session, this is to introduce the pulse discharge sintering process applied for the sintering and/or synthesis of a few representative MAX phases, such as Ti3SiC2, Ti3AlC2, Ti2AlC, Ti2AlN, Cr2AlC, Cr2GaC, Ti2GaC, as well as the MAX‐based solid solutions and some composites. The effects of processing parameters on the synthesis reactions, densification, microstructure, as well as the properties have been investigated. This paper not only briefly reviews our synthesis work on the MAX phases but also presents new results such as the comparison of PDS with conventional hot pressing, the newly obtained results on the synthesis of Cr2GaC, Ti2GaC, as well as some solid solutions and composites. With the results presented herein as summarized in tables and figures, none of which were published elsewhere, this article aims at a better understanding of the PDS process in the research and development of the MAX phases and related materials.

“…The introduction of secondary phase as reinforcement into Ti 3 SiC 2 has been proved to be an effective approach to overcome these disadvantages. For example, numerous reinforcements, including TiB 2 [9], SiC [10], c-BN [11], TiC [12], Al 2 O 3 [13] and ZrO 2 [14], have been introduced to improve the mechanical properties of Ti 3 SiC 2 . Commonly, the additions of ceramic particles can improve Vickers hardness and exural strength of Ti 3 SiC 2 matrix composites.…”

“…For example, Górny et al [9] reported that the addition of TiB 2 could effectively improve the Vickers hardness and elastic modulus of Ti 3 SiC 2 . Tian et al [12] prepared Ti 3 SiC 2 -TiC composites and found that the Vickers hardness of the composite increased with increasing TiC content up to 90 vol.%, the exural strength was enhanced by 64% when the content of TiC was 50 vol.%. Wang et al [13] Carbon bers, with numerous attractively comprehensive properties, such as low density, high strength and modulus, excellent chemical inertness and small thermal expansion coe cient, are considered to be the most promising reinforcing phase for many structural ceramics [15][16][17].…”

In this paper, short-carbon-fibers (Csf) reinforced Ti3SiC2 matrix composites (Csf/Ti3SiC2, the Csf content was 0, 2, 5 and 10 vol.%) were fabricated by spark-plasma-sintering (SPS) using Ti3SiC2 powders and Csf as starting materials at 1300 oC. The effects of Csf addition on the phase compositions, microstructures and mechanical properties (including hardness, flexural strength and fracture toughness) of Csf/Ti3SiC2 composites were investigated. The Csf, with a bi-layered transition layers, i.e. TiC and SiC layer, were homogeneously distributed in the as-prepared Csf/Ti3SiC2 composites. With the increase of Csf content, the fracture toughness of Csf/Ti3SiC2 composites increased, but the flexural strength decreased, while the Vickers hardness decreased initially then increased steadily when the Csf content was higher than 2 vol.%. These changed performances could be attributed to the introduction of Csf and the formation of much stronger interfacial phases.
