Journal ArticleDOI
High temperature materials for aerospace applications: Ni-based superalloys and γ-TiAl alloys
TL;DR: In this paper, the single-crystal nickel-based superalloys for high-pressure turbine blades and the γ-TiAl-based alloys for low pressure turbine blades are presented.
Journal ArticleDOI
Microstructures and deformation mechanisms of a G4 TiAl alloy produced by spark plasma sintering
Houria Jabbar,Houria Jabbar,Jean-Philippe Monchoux,Jean-Philippe Monchoux,Marc Thomas,Alain Couret,Alain Couret +6 more
TL;DR: In this paper, a double phase γ+α 2 microstructure containing B2 precipitates is found in a large range of sintering temperatures and the effect of microstructural heterogeneities from the initial powder is demonstrated.
Journal ArticleDOI
Reduction of the hot cracking sensitivity of CM-247LC superalloy processed by laser cladding using induction preheating
Guillaume Bidron,Anis Doghri,Thierry Malot,Florent Fournier-Dit-Chabert,Marc Thomas,Patrice Peyre +5 more
TL;DR: In this article, a detailed investigation of the effect of cladding parameters on the crack susceptibility was carried out on coupons that received a low pre-heating condition, and attempts were made to reduce crack defects by using an induction preheating, with higher temperatures in the range of 800-1100°C.
Journal ArticleDOI
Effect of ageing on the properties of the W-containing IRIS-TiAl alloy
Alain Couret,David Reyes,Marc Thomas,Nicolas Ratel-Ramond,Christophe Deshayes,Jean-Philippe Monchoux +5 more
TL;DR: In this paper, the effects of ageing at 800 °C on the properties of the IRIS alloy (Ti 49.9 Al 48 W 2 B 0.1) are studied.
Journal ArticleDOI
Impact of β-phase in TiAl alloys on mechanical properties after high temperature air exposure
TL;DR: In this paper, the influence of high temperature air exposure on the tensile properties at room temperature and on the fatigue strength at high temperature of two TiAl alloys, is studied.
