Grinding of Gamma TiAl Intermetallic Alloys

open access: goldProcedia Engineering, 2013
AbstractTitanium intermetallic materials are likely to play a significant role in the production of future aeroengines. Although applicable for only a relatively narrow range of applications, gamma-TiAl intermetallic materials are nonetheless the focus of all leading aerospace/gas turbine manufacturers, as a replacement for some nickel-based superalloy

Development of TiAl–Si Alloys—A Review [PDF]

open access: yesMaterials, 2021
This paper describes the effect of silicon on the manufacturing process, structure, phase composition, and selected properties of titanium aluminide alloys. The experimental generation of TiAl–Si alloys is composed of titanium aluminide (TiAl, Ti3Al or TiAl3) matrix reinforced by hard and heat-resistant titanium silicides (especially Ti5Si3).
