“…While hot-pressing has remained an important method for bulk synthesis [203,204,205,206,207,208] for research purposes, pressureless sintering [209,210,211,212,213,214,215] may be more commercially viable. Other methods for processing of bulk MAX phases are variations of self-propagating high-temperature synthesis [216,217,218,219,220], spark plasma sintering [221,222,223,224,225] or pulse discharge sintering [226,227,228,229,230,231], and solidliquid reaction synthesis [232,233,234]. Recent innovative approaches to bulk synthesis include three-dimensional printing [235], the use of Al or Sn, respectively, as catalysts for growth of 38 Ti 3 SiC 2 and Ti 3 AlC 2 [210,236,237], and design of crystalline precursors for solid phase reaction synthesis [238].…”

This article is a critical review of the M n+1 AX n phases ("MAX phases", where n =1, 2, or 3) from a materials science perspective. MAX phases are a class of hexagonal-structure ternary carbides and nitrides ("X") of a transition metal ("M") and an A-group element. The most well known are Ti 2 AlC, Ti 3 SiC 2 , and Ti 4 AlN 3 . There are ~60 MAX phases with at least 9 discovered in the last five years alone. What makes the MAX phases fascinating and potentially useful is their remarkable combination of chemical, physical, electrical, and mechanical properties, which in many ways combine the characteristics of metals and ceramics. For example, MAX phases are typically resistant to oxidation and corrosion, elastically stiff, but at the same time they exhibit high thermal and electrical conductivities and are machinable. These properties stem from an inherently nanolaminated crystal structure, with M n+1 X n slabs intercalated with pure A-element layers. The research on MAX phases has been accelerated by the introduction of thin-film processing methods.Magnetron sputtering and arc deposition have been employed to synthesize single-crystal material by epitaxial growth, which enables studies of fundamental materials properties. However, the surface-initiated decomposition of M n+1 AX n thin films into MX compounds at temperatures of 1000-1100 °C is much lower than the decomposition temperatures typically reported for the corresponding bulk material. We also review the prospects for low-temperature synthesis, which is essential for deposition of MAX phases onto technologically important substrates. While deposition of MAX phases from the archetypical Ti-Si-C and Ti-Al-N systems typically require synthesis temperatures of ~800 °C, recent results have demonstrated that V 2 GeC and Cr 2 AlC can be deposited at ~450 °C. Also, thermal spray of Ti 2 AlC powder has been used to produce thick coatings. We further treat progress in the use of first-principles calculations for predicting hypothetical MAX phases and their properties. Together with advances in processing and materials 3 analysis, this progress has led to recent discoveries of numerous new MAX phases such as Ti 4 SiC 3 , Ta 4 AlC 3 , and Ti 3 SnC 2 . Finally, important future research directions are discussed. These include charting the unknown regions in phase diagrams to discover new equilibrium and metastable phases, as well as research challenges in understanding their physical properties, such as the effects of anisotropy, impurities, and vacancies on the electrical properties, and unexplored properties such as superconductivity, magnetism, and optics. 4

A new method of synthesizing ceramic composite materials based on Ti 3 SiC 2 using non-powder reaction compositions of titanium and silicon carbide was developed. A ceramic composite with a Ti 3 SiC 2 -TiSi 2 matrix reinforced with SiC particles was obtained by SHS forced compaction of a multilayer packet of regularly packed layers of titanium foil and polymer film filled with silicon carbide particles. The particulars of the phase composition and microstructure of the material obtained were investigated.The innovational potential of Ti 3 SiC 2 -based ceramic materials is due to their unique combination of properties: high resistance to cracking, insensitivity to thermal shock, and good mechanical workability. These properties are mainly due to layered character of the Ti 3 SiC 2 crystalline structure, expressed as a relatively weak bond between carbide layers [Ti 3 C 2 ] ¥¥ and the layers of silicon atoms [Si] ¥¥ separating them. Such a nano-laminated structure makes it possible for Ti 3 SiC 2 grains to deform strongly under a load, localizing the mechanical damage to the material thereby preventing macroscopic fracture [1]. A diagram of the crystalline structure of Ti 3 SiC 2 and the microstructure of its grains is presented in Fig. 1.The high cost and technical complexity of the existing methods of production is holding back the adoption of Ti 3 SiC 2 -based materials in industry: hot isostatic pressing [2 -5], spark plasma sintering [6,7], chemical precipitation from the gas phase [8,9], and so on. Finding technologically efficient and cost-effective methods of production is among the most pressing problems at the present stage of research. A promising approach to solving this problem could be the application of self-propagating high-temperature synthesis (SHS) using layered reaction compositions consisting of a packet of regularly packed reagents in the form of films and foils. For the production of large articles such a technology greatly simplifies the procedure for forming articles, which gives tangible advantages over powder methods,.This article presents the results of laboratory experiments on obtaining Ti 3 SiC 2 -TiSi 2 -SiC ceramics by SHS forced compaction of layered reaction composition Ti-SiC.
