Nanocomposites based on boron carbide B4C are hard materials with wide field of applications in modern technologies. A system first-order ordinary differential equations that simulates the process chemical synthesis nanopowders B4C–TiB2 compositions containing titanium diboride (TiB2) as an additional phase is suggested and resolved numerically for a typical ratio reaction constants. Reagents p...

The structure changes, microstructure evolution, and mechanical properties during Powder Metallurgy (PM) through High Vacuum Sintering of a Ti-TiH2 matrix reinforced with Titanium Diboride (TiB2) particles were investigated. Composites fabricated at 850, 1100, 1300 °C. strategy for the fabrication process was to use PM route employing titanium hydride (TiH2) reduce consumption Commercially Pure...

This research work studies the structural phase parameters and physicomechanical properties of metal-matrix composite materials based on a Ni–TiB2 system obtained by additive manufacturing (specifically, direct laser deposition). The composites were investigated at high temperatures (up to 1000 °C). feasibility fabrication nanostructure alloy with advanced was shown. introduction reinforcing Ti...

We investigate the potential for hydrogen storage of a new class of nanomaterials, metal-diboride nanotubes. These materials have the merits of a high density of binding sites on the tubular surfaces without the adverse effects of metal clustering. Using the TiB2 (8,0) and (5,5) nanotubes as prototype examples, we show through first-principles calculations that each Ti atom can host two intact ...

A BN-TiB2-TiN composite was produced via reactive sintering of the hexagonal BN (hBN) with 20 wt% Ti. Spark plasma (SPS) used as fabrication method and sample characterized by X-ray diffractometry, energy-dispersive spectroscopy, scanning electron microscopy. According to results, Ti utterly consumed during SPS, led in-situ TiB2 TiN0.9 formations. Additionally, microstructural study revealed nu...
