Long-term creep behaviour of cast TiAl-Ta alloy

Intermetallics, 2018
Abstract The long-term creep behaviour of the cast Ti-44.4Al-8.1Ta (at.%) alloy with an initial γ-TiAl(L10)+α2-Ti3Al(D019) microstructure was investigated at 700 °C. The alloy shows a remarkable creep resistance. The minimum creep rate is measured to be as low as 1.47 × 10−10 s−1 and total deformation is only 2.5% after an interrupted 30000 h creep ...

Omega phase in as-cast high-Nb-containing TiAl alloy

Scripta Materialia, 2013
The omega phase in as-cast high-Nb-containing TiAl alloy exhibits particles with sizes on the nano- or microscale within the B2 matrix. Omega particles are transformed from the B2 phase by heterogeneous nucleation on the B2/γ boundaries or homogeneous nucleation within the B2 phase. After annealing at 900 °C, the omega particles disappear and transform

Effect of TiB2 addition on microstructure and fluidity of cast TiAl alloy

Vacuum, 2020
Abstract Effects of TiB2 addition on Microstructure and Fluidity of Ti–48Al–2Cr–2Nb + xTiB2 (x = 0.18, 0.36, 0.54, 0.72, 0.9, 1.8 wt%) alloys fabricated by vacuum non-consumable tungsten arc melting were investigated. Results showed that with adequate TiB2 addition (0.72% TiB2 and more), the as-cast microstructure transformed from coarse columnar ...

Creep behaviour of a cast TiAl-based alloy for industrial applications

Intermetallics, 2006
Abstract The creep behaviour of a cast TiAl-based alloy with nominal chemical composition Ti–46Al–2W–0.5Si (at.%) was investigated. Constant load tensile creep tests were performed in the temperature range 973–1073 K and at applied stresses ranging from 200 to 390 MPa.

Dynamic recrystallization behavior of an as-cast TiAl alloy during hot compression

Materials Characterization, 2014
Abstract High temperature compressive deformation behaviors of as-cast Ti–43Al–4Nb–1.4W–0.6B alloy were investigated at temperatures ranging from 1050 °C to 1200 °C, and strain rates from 0.001 s − 1 to 1 s − 1 . Electron back scattered diffraction technique, scanning electron microscopy and transmission electron microscopy were employed to ...

Tensile Ductility of Cast TiAl Alloys

Materials Science Forum, 2010
The microstructural characteristics and room temperature tensile ductility in some cast TiAl alloys were analyzed. It was found that grain refinement, either through Q&A treatment in boron-free alloys or through low dose of boron addition in beta solidifying alloys with lamellar microstructures, is not sufficient for good ductility. For cast alloys

Mechanical properties of ?-TiAl cast alloys

Metal Science and Heat Treatment, 1996
At present, much attention is being devoted to evaluation of the properties of γ-TiAl alloys in various structural states characteristic for the stage of their production (casting or powder metallurgy) and for subsequent treatment (deformation or heat treatment by various regimes).

The ductility of cast TiAl-based alloys

MRS Proceedings, 2011
ABSTRACTThe factors which influence the ductility of cast samples of TiAl-based alloys are briefly reviewed with emphasis on alloys where microstructural refinement has been used in an attempt to improve ductility. The grain size in cast samples of different TiAl-based alloys can be refined either by high additions of about 1at% boron, or by lower ...
