Title: Cyclic deformation and lattice strain distribution of high Nb containing TiAl alloy

Abstract

Low cycle fatigue of lamellar TiAl with 8.5 at.-%Nb was studied with a total strain amplitude of 0.28% at three temperatures: room temperature, 750°C and 900°C. At room temperature, the material exhibited cyclic hardening and the fracture mode was mainly interlamellar. At 750°C and 900°C, the material showed cyclic softening and the fracture mode was translamellar. The lattice strain in γ phase was almost tensile and larger tensile lattice strain in γ phase seems detrimental. Besides, the opposite direction of {201}_γ and {100}_α2 lead to crack propagation along α₂/γ interfaces. B2/β_o phase always suffered compressive lattice strain in the tests. Finally, the destruction of lamellar microstructure was the reason for colony refinement at 750°C and 900°C.

Microstructure stability and micro-mechanical behavior of as-cast gamma-TiAl alloy during high-temperature low cycle fatigue

Journal Article Ding, Jie ; Zhang, Minghe ; Ye, Teng ; ... - Acta Materialia

This paper systematically investigated the low cycle fatigue deformation of a high Nb-containing TiAl alloy with a nominal chemical composition of Ti-45Al-8.5Nb-0.2W-0.2B-0.02Y at 850 °C by using transmission electron microscopy (TEM), scanning electron microscopy (SEM), and synchrotron-based high-energy X-ray diffraction (HE-XRD) techniques. Cyclic stress-strain (CSS) behavior, lattice strain, and peak broadening of {100}_α2, {201}_γ, and {202}_ωo planes, phase transformations, and crack propagation behavior were obtained for samples with three total strain amplitudes: Δε_t/2 = ±0.25%, Δε_t/2 = ±0.28%, and Δε_t/2 = ±0.30%. At early deformation stages, α_2lamellae transformed into ωo phase with a distinct orientation relationship, and a certain orientationmore »« less

Deformation and fracture behavior in TiAl alloys under monotonic and cyclic loading conditions

Book Kim, Y W ; Dimiduk, D M

Deformation and fracture behavior of two-phase TiAl alloys was investigated under monotonic as well as cyclic tension loading conditions for duplex and lamellar microstructural forms. The Hall-Perch relationship with an abnormally high constant in fully-lamellar material is explained as a combined function of grain-size and deformation-anisotropy characteristic of the lamellar structure. The effects of microstructure on the behavior are compared and analyzed for deformation temperatures below and above the brittle-ductile transition (BDT). The crack initiation toughness and associated strains near the crack tip are used to explain the inverse relationship between ductility and toughness observed at RT. The effect ofmore »« less
Crystallographic features of intralamellar fracture in a fully lamellar TiAl based alloy

Journal Article Huang, Z W ; Bowen, P ; Davey, S ; ... - Scripta Materialia

From fatigue fracture surface examination on fully lamellar microstructure of {gamma}-TiAl alloys, intralamellar crack propagation has been reported recently. Compared with the investigation of translamellar and interlamellar fractures, the characteristic features of intralamellar fatigue fracture have not been investigated in detail. Intralamellar crack propagation on the fatigue fracture surface is found same as interlamellar propagation, parallel to lamellar interfaces but is characterized by complicated geometric patterns of microcracking traces on consecutive lamellar plates, while translamellar propagation occurs transverse to the lamellar boundaries. These geometric patterns may relate to deformation traces occurring in areas local to the growing crack tip. Anmore »« less

Fractographic study of fatigue crack growth processes in a fully lamellar {gamma}-TiAl alloy

Journal Article Balsone, S J ; Worth, B D ; Larsen, J M ; ... - Scripta Metallurgica et Materialia

In the specific TiAl alloy examined in this study, fatigue crack propagation in the fully lamellar microstructure proceeds by three distinct fracture processes: a translamellar mode nominally perpendicular to the lamellar interfaces, an interlamellar mode where crack advance occurs along {gamma}/{gamma}{sub T} or {alpha}{sub 2}/{gamma} interfaces, and an intralamellar mode where crack advanced proceeds along slip planes confined to a single {gamma} lamellae and bounded by {gamma}/{gamma}{sub T} or {alpha}{sub 2}/{gamma} interfaces. The nature of these fracture modes suggest that crack tip deformation is an important part of the fatigue crack growth process. Further studies are underway to delineate themore »« less

Key microstructures controlling the mechanical properties of two-phase TiAl alloys with lamellar structures

Conference Liu, C T ; Maziasz, P J ; Wright, J L

TiAl alloys with the base composition of Ti-47Al-2Cr-2Nb (at.%) were prepared by arc melting and drop casting, followed by hot extrusion above the {alpha}-transus temperature, T{sub {alpha}}. The hot extruded materials were then heat treated above and below T{sub {alpha}} in order to control microstructural features in these lamellar structures. Mechanical properties of these alloys were determined by tensile testing at temperatures to 1000 C. Tensile elongation at room temperature (RT) is strongly dependent on grain size, showing increased ductility with decreasing grain size. Strength at RT and elevated temperatures is sensitive to interlamellar spacing, showing increased strength with decreasingmore »« less
