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...

Ti(C, N)-TiB2 composite cermets with different binders (high entropy alloy (HEA) or Ni-Co) were fabricated by mechanical alloying and vacuum hot-pressing sintering. The wear resistance of the two at elevated temperatures was studied. Wear mechanism characterized a combination scanning electron microscopy energy dispersive spectroscopy. experimental results indicated that HEA binder possessed ex...

To investigate the effect of rare earth on size and distribution TiB2 phase in aluminum alloy refiner, Al-5Ti-1B-RE master was fabricated, its microstructure constitutions were investigated by combination first principles calculations experimental investigation. The calculated results reveal that Ce has most effective modification ability due to positive adsorption energy largest charge transfe...

Metal matrix composites (MMCs) attract considerable attention as a result from its ability in providing a high strength, high modulus, high toughness, high impact properties, improving wear resistance and providing good corrosion resistance compared to unreinforced alloy. Aluminium Silicon (Al/Si) alloy MMC has been widely used in various industrial sectors such as in transportation, domestic e...
