“…As is seen from the microstructure images, targeted TiB 2 phases were obtained in all microstructures. This situation was supported by current studies in the literature [3,19,[20][21][22][23][24][25], EDX analysis results (Table 5) and X-ray analysis results (Fig. 7) proved and supported the presence of TiB 2 in hardfacings.…”

In this study, four hardfacings, reinforced with in-situ synthesized TiB2 particles, were cladded by tungsten inert gas (TIG) welding, applying flux-cored wires with varying Fe-Ti and Fe-B content. Microstructural examination, macrohardness and microhardness measurements and abrasive wear tests were performed. Morphology of TiB2 changed from a small-sized hexagonal and rectangular to a coarse plate-like one with the increasing common proportion of titanium and boron. Accordingly, hardness and wear resistance increased linearly with the changing titanium and boron content in hardfacings.K e y w o r d s: TiB2, wear, microstructure, hardfacing, flux-cored wire

“…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.

“…Due to extraordinary microhardness (34.0GPa), outstanding tribological properties [1][2][3][4], low density (4.52g/cm 3 ), and good thermal and electrical conductivity [5][6][7][8][9] (60W/m -1 K -1 ) [10], the TiB 2 is considered as a ceramic phase reinforcing advanced cermets [6,11]. The Young's modulus (E) of 529GPa [3] and transverse rupture strength of even 1500MPa [4] can be reached for nearly monolithic TiB 2 material.…”

“…Particular attention is being paid to Al [15][16][17][18], Cu or Fe as a toughening binder [2,6,8,11,[19][20][21], because cermets can be obtained in these systems. In order to fully utilize the high refractoriness of TiB 2 (melting point of 3225°C), Fe is a better candidate for a metallic matrix.…”

“…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.…”
