“…To date, the main research in the field of MAX phases of the Ti-Al-C system can be divided into two main groups: the synthesis and the creation of composite materials based on MAX phases. Synthesis studies imply the optimization of the experimental parameters to obtain MAX phases, and research in this area is associated with high-temperature processes, such as self-propagating high-temperature synthesis (SHS) [8][9][10] and spark plasma sintering (SPS) [11][12][13], as well as synthesis processes under pressure, such as hot isostatic pressing (HIP) [14][15][16]. Such technologies have a number of disadvantages-in particular, low productivity at a high cost.…”

“…The direction of the study of composites includes complex structural studies and mechanical testing of materials containing the Ti-Al-C system in the composition of the MAX phase together with other compounds, mainly including TiC [17] and intermetallic compounds of the Ti-Al system [15,18]. These compounds are used because they can be obtained as reaction products in the Ti-Al-C system, which simplifies the synthesis of a composite material.…”

Powder injection melting (PIM) and material extrusion additive manufacturing (MEAM) are promising production technologies that allow us to obtain products from modern composite materials. These technologies make it possible to obtain products of complex shape from ceramic composite materials, which is a non-trivial task. A highly filled polymer feedstock is used as a source material in such technologies. In this work, a study of the structures and properties of samples obtained from SiC-Ti3AlC2 and TiC-Ti3AlC2 feedstocks by the PIM method was performed. The main purpose of this work was to study the influence of the powder compositions in feedstocks on the rheological properties and the structures of the obtained samples, as well as to determine the sintering parameters of samples of these compositions. In the future, it is planned to use the received and studied feedstocks in material extrusion additive manufacturing (MEAM). It was found that the investigated compositions had different MFI values depending on the composition. The effect of the sintering parameters on the structure and properties was shown. During the sintering of SiC-Ti3AlC2 ceramics in the temperature range of 1200–1400 °C in a vacuum, the main components of the mixture interacted with the formation of Ti3SiC2 and TiC. For materials of the TiC-Ti3AlC2 composition, partial oxidation of the material and the formation of titanium and aluminum oxides was observed.

TiC–Ti–Al mixed powders and TC4 titanium alloy foils were overlapped layer-by-layer in the graphite die. The TC4-based laminated composite sheets reinforced by Ti aluminide and carbide were successfully fabricated via spark plasma sintering (SPS) at 1100 °C with a well-bonded interface. The composite layers were mainly composed of TiAl, Ti3Al, Ti2AlC, and Ti3AlC2 phases. The carbides particles distributed in the matrix played an important role in the deflection of cracks and the passivation of microcracks. TC4 titanium alloy layers had an obvious effect on the stress distribution during the loading process, and provided an energy dissipation mechanism, which could improve the mechanical properties of the laminated composite sheets obviously. When the theoretical amount of Ti2AlC was 20 wt %, the flexural strength and fracture toughness of the laminated composite sheets reached the maximum value in the arrester direction, which were 1428.79 MPa and 64.08 MPa·m1/2, respectively.

“…The in situ fabrication method is known to be extremely effective for producing a fine and homogeneous distribution of particulate reinforcements in a matrix [2][3][4][5][6][7]. It usually includes the synthesis of a dispersoid phase within a matrix enthalpy value [10][11][12], the formation of nanostructured powders [13], good sinterability [14], and etc.…”

Fe-TiB2 powder was synthesized in-situ by the planetary ball milling and subsequent heat-treatment of an iron boride (FeB) and titanium hydride (TiH2) powder mixture. Mechanical activation of the (FeB+TiH2) powder mixtures was observed after a milling time of 3 hours at 700 rpm of rotation speed, but activation was not the same after 1 hour milling time. The particle size of the (FeB+ TiH2) powder mixture was reduced to the nanometer scale, and each constituent was homogeneously distributed. A sharp exothermic peak was observed at a lower temperature (749 ℃) on the DSC curves for the (FeB+TiH2) powder mixture milled for 3 hours, compared to the one milled for 1 hour (774 ℃). These peaks were confirmed to have resulted from the formation reaction of the TiB2 phase, from Ti and B elements in the FeB. The Fe-TiB2 composite powder fabricated in situ exhibited only two phases of Fe and TiB2 with homogeneous distribution. The size of the TiB2 particulates in the Fe matrix was less than 5 nm.
