Nanocrystalline titanium aluminide

Acta Metallurgica et Materialia, 1994
TiAl 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,

Nanostructured titanium aluminides

Materials Science and Engineering: A, 1994
Abstract Binary TiAl and ternary TiAlNb 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 ...

Gamma titanium aluminide, TNB

Intermetallics, 2005
Abstract A range of mechanical properties for wrought TNB alloy (Ti–45Al–8Nb–0.2C%) and cast Ti4522XD(Ti–45Al–2Nb–2Mn–XD) have been assessed. The influence of notch sensitivity on fatigue strength has been evaluated and compared in terms of different microstructure and alloy composition.

XD™ Titanium Aluminide Composites

MRS Proceedings, 1988
AbstractThe advantages of reinforcing metals with ceramic particles to produce metal matrix composites are well known. The behavior of discontinuously reinforced intermetallic compounds, however, has not been extensively studied. Martin Marietta Laboratories has produced a new generation of discontinuously reinforced titanium aluminide composites using

Processing titanium aluminide foils

JOM, 1989
In an effort to extend the available manufacturing technologies for Ti3Albase aluminides, the potential success of a new hot-rolling process for the production of high-quality foils has been investigated. Processing of Super-α2 aluminide foils approximately 0.15 mm thick takes full advantage of the combined benefits of controlled rolling and a unique ...
