“…In situ Fe-TiB 2 composites have been fabricated using various methods, such as laser cladding [2,3], plasma transferred arc (PTA) [4,5], aluminothermic reduction [6], spark plasma sintering (SPS) [7], and self-propagating high-temperature synthesis (SHS) [8][9][10][11]. In our previous work [12], Fe-TiB 2 powder was synthesized in situ from an iron boride (FeB) and titanium hydride (TiH 2 ) powder mixture by planetary ball-milling and subsequent heat treatment.…”

The in situ formation of TiB 2 particulates via an interface reaction between Ti and FeB powders was studied. The effects of mechanical activation by high-energy milling on the decomposition of TiH 2 and the interface reactions between Ti and FeB powders to form TiB 2 were investigated. Powder mixtures were fabricated using planetary ball-milling under various milling conditions. The specific ball-milling energy was calculated from the measured electrical power consumption during milling process. High specific milling energy (152.6 kJ/g) resulted in a size reduction and homogeneous dispersion of constituent powders. This resulted in a decrease in the decomposition temperature of TiH 2 and an increase in the formation reaction of TiB 2 particulates in the Fe matrix, resulting in a homogeneous microstructure of nanoscale TiB 2 evenly distributed within the Fe matrix. In contrast, the powder mixture milled with low specific milling energy (36.5 kJ/g) showed an inhomogeneous microstructure composed of relatively large Fe-Fe 2 B particles surrounded by a thin layer of Fe-TiB 2 within a finely dispersed Fe-TiB 2 matrix region.

“…Therefore, the TiB 2 -based cermets for those investigations were prepared using SHS under a high pseudo-isostatic pressure, which is one of the most progressive and energy saving methods to obtain TiB 2 and TiB 2 -reinforced materials [2,[23][24][25]. Such method was also used to fabricate the composites used in the previous study [12,20,25], especially that the Ti excess can be easily controlled by using the mixtures of elemental (Ti, B, Fe) powders.…”

“…The structure contains areas with the fine-grained titanium diboride and adjusting areas from alumina-magnesia spinel (Figure 2c). Depending on their content, different metal alloys partially or fully surround particles of titanium borides [8,9]. Studies on the microstructure of the composite blends based on TiB2 with different MgAl2O4 compositions showed that, depending on the amount of added spinel, the composite structure change (Figure 2).…”

Metal borides are widely used as heat-insulating materials, however, the range of their application in high-temperature conditions with oxidative medium is significantly restricted. To improve the thermal stability of structural materials based on titanium boride, and to prevent the growth of TiB 2 crystals, additives based on alumina-magnesia spinel with chemical resistant and refractory properties have been used. The aim of this work is to study the structure of TiB 2 with alumina-magnesia spinel additives obtained by self-propagating high-temperature synthesis (SHS). TiB 2 structure with uniform fine-grained distribution was obtained in an MgAl 2 O 4 matrix. The material composition was confirmed by X-ray diffraction analysis (DRON-3M, filtered Co kα-emission), FTIR spectroscopy (Thermo Electron Nicolet 5700, within the range of 1300-400 cm −1 ), and scanning electron microscopy (Philips SEM 515). The obtained material represents a composite, where the particles of TiB 2 with a size of 5 µm are uniformly distributed in the alloy of alumina-magnesia spinel.
