Mechanical alloying of AlTi alloys

Materials Science and Engineering: A, 1990
Abstract Mechanical alloying has been used to mix elemental powders of aluminium and titanium and to produce mixtures of aluminium and Al 3 Ti phases during heat treatments for consolidation. Alloy concentrations of 12.5–26 at.% Ti have been covered, corresponding to alloys containing 50–100 at.% Al 3 Ti after reaction.

Grindability of Ti alloys

Metallurgical and Materials Transactions A, 2006
The grindability of Ti-based alloys was analyzed by considering the fracture behavior of individual alloys in response to the stress field of a grinding wheel. First, the stress field under a grinding wheel was computed by treating the grinding wheel as a cylindrical disk with a flat region acting on a flat substrate.

Structural Characterization of Alloyed Al/Ti and Ti Contacts on SiC

Materials Science Forum, 2004
In this work a structural characterisation of Al-rich (72 wt. % Al) Al/Ti alloyed electrical contact on SiC is presented and compared with that obtained on Ti alloyed contacts. Rutherford Back Scattering in the Channelling mode (RBS-C) and Transmission Electron Microscopy of cross-sectioned specimens (XTEM) in various analysis modes were used as ...

Thermodynamic properties of Ti in Ag–Ti alloys

Materials Science and Engineering: A, 2000
Abstract The thermodynamic properties of Ti in Ag–Ti alloys at 1273 K were determined using an oxygen sensor employing ZrO 2 (2.14 wt% MgO) as the solid electrolyte. TiO was identified as the equilibrium phase in the interface reaction layer formed by the reaction of Ti with Al 2 O 3 at 1273 K. From the standard Gibbs energy of formation of TiO and

Microstructural and Mechanical Investigations of Friction Stir Welded TI/TI- And TI-Alloy/TI-Alloy-Joints

2013
Friction Stir Welding (FSW) is an efficient welding technique to join light-weight materials in ductile material condition. Especially for aerospace applications FSW of cp-titanium and Ti-alloys is of high scientific and technological interest. At the Institute of Materials Science and Engineering (WKK) friction stir welds of 1.2 mm thick cp-titanium ...

Development of dental Pd−Ti alloys

Dental Materials, 1985
Abstract Alloys, in which the main constituents are palladium and titanium, have the following potential advantages for dental application: corrosion resistance, biocompatibility and acceptable casting temperatures for porcelainfused-to-metal dental prostheses. Alloy compositions chosen for investigation were as follows: 30 w/o Ti which lies in the 5%

Grindability of cast Ti–Hf alloys

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005
AbstractAs part of our systematic studies characterizing the properties of titanium alloys, we investigated the grindability of a series of cast Ti–Hf alloys. Alloy buttons with hafnium concentrations up to 40 mass% were made using an argon‐arc melting furnace.

Thermochemical Nitriding and Oxynitriding of Ti Alloys

Journal of Nanoscience and Nanotechnology, 2019
Nitrided and oxynitrided coatings that formed on α alloy (c.p.-Ti), near-α alloy (Ti-2.1Al-2.5Zr), (α + β) alloy (Ti-6Al-4V), and β alloy (Ti-6Al-2Zr-1Mo-1V) were microstructurally characterized. The nitriding at 950 °C and PN₂ ═ 105 Pa for 5 h formed TiN, Ti₂N, and α-Ti(N) layers from the surface.

Thermomechanical study of Ni‐Ti alloys

Journal of Biomedical Materials Research, 1988
AbstractA preliminary study was conducted to demonstrate the usefulness of the combined technique of differential scanning calorimetry (DSC) and mechanical testing for the shape memory metals of 54NiTi and 53NiTiCo(3%) alloys. The DSC technique was used to measure precise transformation temperatures and the amount of thermal energy required for the ...

Studies of Al-Ti Alloys by SEM

AIP Conference Proceedings, 2007
Al‐Ti (1, 2 wt. %) alloys were investigated by Scanning Electron Microscopy (SEM). SEM observations and energy‐dispersive x‐ray analyses (EDX) showed that the phase structure of Al‐Ti (1 %) alloy at 165 μm/s is composed of Al matrix and C, Ni, Fe and Si particles and the Al‐Ti (1 %) alloys at 16 and 8 μm/s have only the Al matrix and C particles.
