For the CM under consideration, when reinforcing titanium and its alloys, molybdenum wire, sapphire fibers, silicon carbide and titanium boride are used.
Textured factor can be used to intensify boriding in the formation of hardened layers based either on titanium boride, or on a solid boron solution in titanium.
This is due to a change of the phase composition of the titanium boride layer.
In this case of hardening, the hardened zone is a solid solution of boron in [alpha]-titanium and a small amount of titanium borides Ti[B.sub.2] and TiB in the surface layer (Fig.
The titanium boride (TiB) reinforcing phase was formed in situ in the clad layer during the cladding process.
The interlocking effect between needle titanium boride (TiB) and the matrix is weaker because of the geometric characteristics of the needle shape.
Less distributed are coatings from hafnium nitrides and carbides, chromium and zirconium carbides, titanium boride, etc.
Ladle treatment includes a magnesium trimming addition, titanium boride (TiB) grain refinement, strontium modification, fluxing and rotary degassing to reduce levels of H gas and non-metallic inclusions.

Titanium boride particles are hexagonal shape, with almost echiaxa shape, and are situated at the grain boundaries.
The combination of these properties makes titanium borides promising materials for multifunctional applications, for example, electrode materials, cutting tools, wear-resistant parts, protecting coatings, and all kinds of high-temperature structural components [3].
So far, a number of theoretical and experimental works have been done to investigate the structural, electronic, and elastic properties of titanium borides [7-11], leaving their dynamical properties highly unexplored [12, 13].
