Comparative study of the compression properties of TiAl matrix composites reinforced with nano-TiB2 and nano-Ti5Si3 particles

“…It has been proved that the composite technology is an effective approach to enhance the strength of the TiAl intermetallics by introducing the stiff and hard particle reinforcements [6][7][8][9][10][11]. Nevertheless, the strength enhancement of the TiAl matrix composites by the addition of these particles is usually at the cost of the ductility [8][9][10][11].…”

The effect of using repetitively pulsed laser radiation in selective laser melting when creating a metal-matrix composite Ti-6Al-4V–B4C

“…Titanium is a very promising material, which is characterized by the highest strength-to-weight ratio among metals, along with high corrosion resistance [7][8][9][10][11]. Sintered composites based on B 4 C, TiC, TiB, TiB 2 ceramics and titanium metal binder have demonstrated good performance due to their high compatibility, high melting point, extreme hardness, excellent wear resistance and corrosion resistance, combined with excellent fracture toughness [12][13][14][15][16][17]. These composites are mainly obtained by hot pressing or casting.…”

Ceramic-Reinforced γ-TiAl-Based Composites: Synthesis, Structure, and Properties

“…In most cases, a reinforcing phase was homogeneously distributed in the intermetallic matrix. TiC [18,19,20], Ti 2 AlC [20,21,22], TiB 2 [23], and SiC [24,25] as well as different oxides [18] and nitrides [26,27] have been used as a reinforcement phase. For instance, Yue et al [19] showed that the addition of 5 vol% TiC to γ-TiAl alloy increased its crack grow resistance by almost 45%.…”

“…Increasing the volume fraction of hard particles in the structure of the material (up to 20–40%) positively influenced the wear resistance of the intermetallic material. A γ-TiAl—TiB 2 composite has been reported to have high strength characteristics both at the room and elevated temperatures, with the maximum strength being observed for 10 vol% of the reinforcement phase [23].…”
