A metal-carbide-intermetallic material based on combustion products of the layer system (Ti-Al-Si)/(Ti-C)/Ti was for first time obtained with help self-propagating high-temperature synthesis (SHS) combined pressing. Exothermic from elementary powders carried out at a pressure 10 MPa, and pressing hot product 100 MPa. It has been shown that SHS contributes to formation permanent joints «metal/ca...

We use hybrid density functional calculations to assess n-type doping in monoclinic (Al$_x$Ga$_{1-x}$)$_2$O$_3$ alloys. focus on Si, the most promising donor dopant, and study structural properties, formation energies charge-state transition levels of its various configurations. also explore impact C H, which are common impurities metal-organic chemical vapor deposition (MOCVD). In Ga$_2$O$_3$,...

Different reducing agents (B, Al, Si and Ti) were individually added to two gypsum-bonded investments to prepare investments preventing surface blackening of some noble cast alloys. The effect of different additive contents on green-body and burnout compressive strength, setting and thermal expansion of the investments were evaluated. The strength and expansion of the investments were changed b...

A special form of laser spot welding is introduced to overlap dissimilar welding of titanium (G2) to 3105-O aluminum alloy. A welding tactile seam tracking design using following pulses that result to a circular seam leads to spot like shape laser welding. This technique was conducted to joint overlapped grad 2 Titanium alloy (Ti G2) to 3105-O Al alloy, with 1, and 0.5 mm thicknesses respective...

The purpose of this investigation was to develop a coating technique and to study the characteristics of titanium–aluminum nitride [(Ti,Al)N] films deposited on a base-metal alloy (Wiron88R) substrate. Titanium–aluminum nitride thin films were deposited on the alloy surface using a reactive radiofrequency sputtering method. The electrochemical properties of three specimens with and without coat...

Spin-to-charge conversion (SCC) involving topological surface states (TSS) is one of the most promising routes for highly efficient spintronic devices terahertz (THz) emission. Here, THz generation generally occurs mainly via SCC consisting in dynamical spin injection into spin-locked TSS. In this work, we demonstrate sizable emission from a nanometric thick insultator (TI)/ferromagnetic juncti...

Superplastic sheet thermoforming has been identified as a standard processing route for the production of complex shapes, especially in the aerospace industry. Ti-Al-Mn (OT4-1) alloy is currently being used for aero engine components as well as other aerospace applications by forming through a conventional route which is typically cost, labour and equipment intensive. The Ti-Al-Mn alloy (made a...
