“…There are several powder metallurgy methods to synthesize the bulk Ti 2 AlN MAX phase, starting with the combination of Ti/Al (using N 2 atmosphere), Ti/AlN or Ti/Al/TiN as raw materials, including hot isostatic pressing (HIP) [ 12 , 13 ], self-propagating high-temperature synthesis (SHS) [ 14 , 15 , 16 , 17 ], mechanical alloying (MA) and hot pressing (HP) [ 18 ], SHS and HP [ 19 ], HP [ 20 , 21 , 22 , 23 ], reaction sintering [ 24 , 25 ] and spark plasma sintering (SPS) [ 26 , 27 , 28 , 29 , 30 ]. Among them, the SPS demonstrates economic and technological advantages in the processing and formation of single phases, such as shorter soaking time, lower sintering temperatures, higher density and densification rate, improved mechanical properties, and refined grain sizes [ 31 ].…”

MAX phases are an advanced class of ceramics based on ternary carbides or nitrides that combine some of the ceramic and metallic properties, which make them potential candidate materials for many engineering applications under severe conditions. The present work reports the successful synthesis of nearly single bulk Ti2AlN MAX phase (>98% purity) through solid-state reaction and from a Ti and AlN powder mixture in a molar ratio of 2:1 as starting materials. The mixture of Ti and AlN powders was subjected to reactive spark plasma sintering (SPS) under 30 MPa at 1200 °C and 1300 °C for 10 min in a vacuum atmosphere. It was found that the massive formation of Al2O3 particles at the grain boundaries during sintering inhibits the development of the Ti2AlN MAX phase in the outer zone of the samples. The effect of sintering temperature on the microstructure and mechanical properties of the Ti2AlN MAX phase was investigated and discussed.

“…Although Ti 2 AlC 0.5 N 0.5 in Table 3 has higher mechanical properties than both Ti 2 AlC and Ti 2 AlN, the grain size of Ti 2 AlN was much larger than those of Ti 2 AlC and Ti 2 AlC 0.5 N 0.5 [110]. It has been reported that the Vickers hardness of the HP-ed Ti 2 AlN bulk samples using SHS-ed Ti 2 AlN powders with a size of 17 μm reaches 5.8 GPa [118]. The SPS-ed Ti 2 AlN bulk samples with a grain size of 5~10 μm has a Vickers hardness higher than 6 GPa [119].…”

MAX phases are a family of ternary carbide or nitride ceramics possessing a layered crystal structure and, due to their chemical bonds having a mixed covalent-ionic-metallic nature, have unique properties combining those of metals and ceramics. In this review, the formation mechanisms of MAX phases from elemental and compound powders are reviewed in detail, as the formation mechanisms are closely related to the unique properties of wellsynthesized MAX phases. The stability of MAX phases in some harsh external environments is significantly influenced by the defect population, allowing the mechanisms of defect formation and migration to strongly influence their self-healing performance and radiation tolerance. The properties of MAX phases can be tailored by creating solid solutions, which have lattice distortions, and texturing which results in the preferential orientation of plate-like grains.

“…The method and materials produced are described in details in the section ‘SHS-ceramics’ of this review. Another promising method for densification of CS products is a combination of SHS with HP and HIP [32–35]. SHS with extrusion is an approach for the production of fully dense materials with large aspect ratios [36–38].…”

Self-propagating high-temperature synthesis (SHS) or combustion synthesis (CS) is a rapidly developing research area. SHS materials are being used in various fields, including mechanical and chemical engineering, medical and bioscience, aerospace and nuclear industries. The goal of the present paper is to provide a comprehensive state-of-the-art review and to analyse a critical mass of knowledge in the field of SHS materials and coatings. We also briefly discuss the history and scientific foundations of SHS along with an overview of the technological aspects for synthesis of different materials, including powders, ceramics, metal-ceramics, intermetallides, and composite materials. Application of CS in the field of surface engineering is also discussed focusing on two main routes for applying SHS to coating deposition: (i) single-step formation of the desired coatings and (ii) use of SHSderived powders, targets or electrodes in the coating deposition processes.
