Effects of titanium diboride on the mechanical

For the first time, this work purposes a novel composite production from alumina-toughened zirconia titanium diboride (ATZ-TiB2). In designing the composites, the matrix was composed of 3 mol % yttria (Y2O3) stabilized tetragonal zirconia polycrystalline (3Y-TZP) and 8 mol % magnesia (MgO) partially stabilized zirconia (8 Mg-PSZ) phases at an equal molar ratio. Besides, alumina (α-Al2O3) and TiB2 were added to the 3Y-TZP/8 Mg-PSZ matrix with one wt% and 0.5–2 wt% ratios, respectively. The compos

Titanium diboride composite with improved sintering characteristics

Titanium diboride (TiB2) and its ceramic composites were prepared by hot pressing. The sintering process, phase evolution, microstructure, and mechanical properties of TiB2 ceramics prepared by using different milling media materials: tungsten carbide (W.C./Co) or SiAlON was studied. It was found that the inclusion of W.C./Co significantly improved the sinterability of the TiB2 ceramics. A core/rim structure was identified with pure TiB2 as the core and W-rich TiB2, i.e., (Ti, W)B2 as the rim. M

American Elements can produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies. American Elements produces many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural, and Pharmaceutical Grade; Optical Grade, USP and EP/BP (Euro

Strength of Titanium diboride

Proceeding from the results of the previous subsection, let us restrict our attention to specimens with a density of (4.50±0.05) g/cm3 and consider the flexural strength σf of the material. A significant dependence on the grain size is readily seen in the results at room temperature. While this figure contains a mixture of data from three-point and four-point test methods using differing specimen sizes and crosshead speeds, the comparison suggests that the strength σf decreases as the grain size

Mechanical and Thermal Properties of Titanium diboride

The diversity of the processing conditions is a significant factor in the often widely varying property values reported in the literature for polycrystalline TiB2. In this section, the available mechanical and thermal properties are examined to provide a better understanding of how the properties depend on the composition, grain size, and density of the material. For isotropic polycrystalline materials, the elastic properties may be expressed in terms of two independent moduli, the elastic modul

The physical, mechanical, and thermal properties of polycrystalline TiB2 are examined with an emphasis on the significant dependence of the properties on the density and grain size of the material specimens. Using trend analysis, property relations, and interpolation methods, a coherent set of trend values for the properties of polycrystalline TiB2 is determined for a mass fraction of TiB2 ⩾ 98 %, a density of (4.5±0.1) g/cm3, and a mean grain size of (9±1) µm. Titanium diboride (TiB2) is well-k

Potential applications of Titanium diboride

The current use of TiB2 appears to be limited to specialized applications in such areas as impact-resistant armor, cutting tools, crucibles, neutron absorbers, and wear-resistant coatings. TiB2 is extensively used for evaporation boats for the vapor coating of aluminum. It is an attractive material for the aluminum industry as an inoculant to refine the grain size when casting aluminum alloys because of its wettability, low solubility in molten aluminum, and good electrical conductivity. Thin fi

Titanium diboride

Titanium diboride (TiB2) is an extremely hard ceramic with excellent heat conductivity, oxidation stability, and wear resistance. TiB2 is also a reasonable electrical conductor,[1] so it can be used as a cathode material in aluminum smelting and can be shaped by electrical discharge machining. TiB2 shares some properties with boron carbide and titanium carbide, but many of its properties are superior to those of B4C & TiC. Concerning chemical stability, TiB2 is more stable in contact with pure i

Key Properties of Titanium Diboride

What is Titanium diboride?Titanium Diboride (TiB2) is a hard material with high strength and wear resistance at elevated temperatures. The high density, elastic modulus, and compressive strength have led to its use in armor components. It is unaffected by most chemical reagents and has excellent stability and wettability in liquid metals such as zinc and aluminum. This, along with its high electric conductivity, has led to its use in Hall- Héroult cells for aluminum production. It is also used a

Material Description of Titanium diboride

What is Titanium diboride?Titanium diboride (TiB2) is well-known as a ceramic material with relatively high strength and durability as characterized by the relatively high values of its melting point, hardness, strength-to-density ratio, and wear resistance. However, the current use of this material appears to be limited to specialized applications in such areas as impact-resistant armor, cutting tools, crucibles, and wear-resistant coatings. An important evolving application is using TiB2 catho

What is Titanium dioxide

Titanium dioxide (TiO2) is a fine white powder or dust that occurs naturally. It was first intentionally produced for use as a white pigment in 1923. It is naturally opaque and bright, which makes it useful for use in paper, ceramics, rubber, textiles, paints, inks, and cosmetics. Titanium dioxide is also a UV filter and an effective active ingredient in sunscreens. Exposure can irritate the eyes, nose, and throat since it has been shown to cause lung cancer in animals.
