Review of alloy and process development of TiAl alloys

Intermetallics, 2006
Abstract The improved understanding of the factors that control microstructure and properties of TiAl alloys is reviewed together with current work aimed at developing both wrought and cast products. It is suggested that the choice of alloy composition is perhaps far simpler than the complex literature would suggest and the factors that underlie ...

Microstructural Studies of the Deformation of TiAl Alloys

MRS Proceedings, 1988
ABSTRACTThe mechanical behavior and microstructures of TiAl alloys after tensile and bend tests at room temperature and elevated temperatures were studied. The results for two-phase Ti52Al48 alloys are compared with those of single phase Ti48Al52, and the effect of adding 3 at. pct. vanadium as a substitute for Ti in these two alloys is considered.

Laser metal deposition of tial alloys

Pacific International Conference on Applications of Lasers and Optics, 2006
Laser Metal Deposition (LMD) is a validated process for repairing aero engine parts and complete components. An increase of specific efficiency of aero engines is achieved by replacement of heavy parts out of Nickel Base Alloys in the HPC (High Pressure Compressor) and LPT (Low Pressure Turbine) sectors by lightweight parts out of TiAl Alloys in ...

Simulation on extrusion process of TiAl alloy

Intermetallics, 2011
Abstract The rigid-plastic finite element Deform-3D software was employed to describe the plastic deformation behavior of TiAl billet (Ti-46.5Al-2.5V-1.0Cr-0.3Ni alloy) during its axisymmetric extrusion through a conical die. Under various extrusion conditions, the present numerical analysis investigated the strain distribution, the damage factor ...

Carbide precipitation in γ-TiAl alloys

Scripta Metallurgica et Materialia, 1992
Carbide precipitation in gamma-TiAl is observed and found to involve the formation of coherent, rod-shaped perovskite precipitates as a metastable transition phase. At temperatures above 750 deg C, the formation of plate-shaped H-phase particles on dislocations and grain boundaries is accompanied by dissolution of the perovskite precipitate dispersions.
