TiC-Ti-Al mixed powders and TC4 titanium alloy foils were overlapped layer-by-layer in the graphite die. The TC4-based laminated composite sheets reinforced by Ti aluminide and carbide were successfully fabricated via spark plasma sintering (SPS) at 1100 °C with a well-bonded interface. The composite layers were mainly composed of TiAl, Ti₃Al, Ti₂AlC, and Ti₃AlC₂ phases. The carbides particles ...

We study the electronic and magnetic states of as-grown annealed $M\text{Fe}_2\text{O}_4$(111)/$\text{Al}_2\text{O}_3$(111) ($M=\text{Co, Ni}$) thin films with various thicknesses grown on Si(111) substrates $\gamma$-$\text{Al}_2\text{O}_3$(111) buffer layers by using x-ray absorption spectroscopy (XAS) circular dichroism (XMCD), to investigate magnetically dead in these films. Although samples...

Being one of the most high-demand structural materials, titanium has several disadvantages, including low resistance to high-temperature oxidation and wear. The properties its alloys can be improved by applying protective intermetallic coatings. In this study, 2 mm thick Ti-Al-Ta Ti-Al-Cr layers were obtained on workpieces a non-vacuum electron-beam cladding. microstructure phase compositions s...

Interdiffusion in multi-phase diffusion couples of polycrystalline Ti and polysynthetically twinned (PST) Ti-49.3 at.% Al, with the diffusion direction parallel to the lamellar planes, is investigated in the temperature range 973 – 1173 K. A reaction zone (RZ) of the α2-Ti3Al phase forms between the end materials and exhibits deeper penetration in the α2 lamellae than in the primary γ lamellae....

Superconductivity in a doped topological insulator (TI) is very interesting phenomenon and constitute new finding of the modern day condensed matter physics. Here we have investigated physical transport properties such an intercalated TI, namely, Bi$_2$Se$_3$ via strong coupling route. The unique bandstructure Bismuth Selenide with dirac cone strongly influenced intercalation by Silver (Ag) (Go...

a low carbon al-killed ti-added steel was produced in mobarakeh steel complex in iran. mechanical properties and microstructural characterizations of steel in the as-cast, hot-rolled, cold-rolled and annealed conditions are presented. dilatometery tests were carried out to measure the finishing and annealing temperatures of steel. it was found that the addition of small amounts of ti increased ...

Mixtures of 47-Al and 53-Ti powders (atomic %) have been consolidated using back pressure equal-channel angular pressing starting with both raw and ball-milled powders. In situ synchrotron high-energy X-ray diffraction studies are presented with continuous Rietveld analysis obtained upon a heating ramp from 300 K to 1075 K performed after the consolidation process. Initial phase distributions c...
