Advanced grinding of titanium aluminides
International Journal of Manufacturing Technology and Management, 2007In aerospace industry, titanium alloys are used for turbine components. The material properties and the specific grinding kinematics enhance the risk of thermally damaging these components. Speed stroke grinding represents an alternative to common grinding strategies while reducing machining time and production cost but simultaneously enhancing the ...

Hydrogenation Of The Titanium Aluminides
MRS Proceedings, 2008AbstractThe hydrogen absorption properties of the Ti-Al-Nb system intermetallics subjected by ball milling were studied. It was found that the hydrogenation of the titanium aluminides during ball milling in hydrogen atmosphere could occur at room temperature without any special requirements to the quality of hydrogen.

Nanostructured titanium aluminides
Materials Science and Engineering: A, 1994Abstract Binary TiAl and ternary TiAlNb alloys were mechanically alloyed in a Szegvari attritor or in a SPEX mill, to produce an amorphous phase and a B2/b.c.c. phase respectively. Consolidation of these powders by hot pressing, explosive compaction or hot isostatic pressing resulted in transformation of the as-milled phases; however, the product ...

Nanocrystalline titanium aluminide
Acta Metallurgica et Materialia, 1994TiAl has potential of being a strong, light-weight structural material. Nanocrystalline TiAl samples were synthesized by sputtering, particle condensation in inert gas and high-pressure compaction of the powder. Structure and chemical composition of individual grains were investigated by X-ray diffraction, conventional transmission electron microscopy,

Microstructure of borides in titanium and titanium aluminides
Proceedings, annual meeting, Electron Microscopy Society of America, 1990The high strength-to-weight ratios and high elevated-temperature strength of dispersion strengthened titanium and titanium aluminides make them attractive materials for aerospace applications. A fine dispersion of hard particles is introduced into these alloys to increase their strength through an Orowan hardening mechanism.

Oxidation subscale of γ-titanium aluminide
Acta Materialia, 1996The subscale formed during high temperature rapid oxidation of gamma-titanium aluminum is revealed by transmission electron microscopy and microanalysis to consist of two phases: one hexagonal with unit cell dimensions a = 0.58 nm, c = 0.47 nm (+/- 0.005 nm), and a composition close to Ti6Al3O4; the other simple cubic with a = 0.69 nm (+/-0.005 nm) and
