Resumen
The ambient temperature fatigue response of the near alpha titanium alloy Timetal 834 has been evaluated using specimens manufactured from two material sources:- hot-rolled barstock and an isothermally forged compressor disc. The effects of dwell periods imposed at peak stress and different R values were assessed. Significant differences were observed between the two alloy variants particularly with respect to their sensitivity to dwell loading. In particular it was found that dwell sensitivity is enhanced by high R values (R = 0.5) and longer dwell times but is reduced by compressive minimum loads (R = -0.5). Variations in microstructural morphology together with differences in localised texture were found to control the contrasting dwell performance in the two materials. Sub-surface fatigue crack initiation has been observed for both coarse grained Timetal 685 and the two Timetal 834 forms. With typical as received hydrogen concentrations of 40-60ppm these initiation sites are characterised by quasi-cleavage facetting. EBSD analysis has demonstrated that the facets are of a near basal orientation with respect to the hexagonal crystal lattice. At high hydrogen concentration in Timetal 685, fractographic and EBSD studies combined with mechanical data from a previous investigation, show that premature fatigue failures are associated with the operation of alternative failure mechanisms. These include strain induced alpha/beta interface cracking and the shear related separation of basal planes. Fatigue crack propagation in the disc material, under dwell and cyclic loading, was explored using three specimen designs: CC, DEN and TDEN. The CC and DEN geometries allowed the behaviour of part through cracks to be evaluated in a uniform stress field and within a plastically deformed stress gradient. The TDEN enabled through section crack behaviour to be quantified. Growth rates were dependent on R-ratio but unaffected by dwell periods at peak load. Increased growth rates at higher R values were attributed to the fact that a high mean stress encourages enhanced strain accumulation and facet formation. The lack of a dwell effect on crack propagation is due to stress relaxation at the crack tip. It could also be associated with compression in the crack tip plastic zone on unloading.

Resumen
High precision uniaxial constant stress tests were carried out for the near-alpha titanium alloy IMI834. Testing was completed at 823, 848, 873, 898 and 923 K, and at stresses chosen to give rupture lives in the range of about one day to six months at each temperature. Over the entire range of testing conditions, predominantly tertiary normal creep curves were recorded. During creep an alpha-case developed at air exposed surfaces, whose depth varied according to a parabolic rate law with an activation energy of 208 kJmol-1. For tests failing after about 1000 hours at 848, 873 and 898 K, and 100 hours at 923 K, failure occurred due to the propagation of circumferential surface cracks which developed in the alpha-case. In contrast, for all tests at 823 K, and for rupture lives of less than 100 hours at 923 K, and for tests lasting less than about 1000 hours at the remaining temperatures, failure occurred due to the link up of creep cavities formed predominantly at the alpha/transformed beta interfaces. A conventional power law analysis of the creep data proved capable of describing the stress and temperature variation of the minimum creep rates and rupture lives. However, this approach gave no information concerning the evolution of creep strain with time. Consequently, the theta-projection concept and the continuum damage mechanics (CDM) constitutive equations were also fitted to the experimental data. Isothermal and anisothermal forms of each model were developed. These proved capable of representing the stress and temperature variation of the experimental failure times, minimum creep rates and failure strains. However, whilst the theta-projection method described entire creep curves, the creep curves constructed using CDM contained almost no primary stage.

Resumen
The premature failure of gas turbine disc components constructed from near alpha titanium alloys under low temperature dwell loading have been attributed to areas of aligned alpha platelets in the specified basketweave microstructure. Attempts at modelling crack initiation within these aligned microstructures has either overlooked the anisotropic nature of alpha titanium or has been restricted by the lack of information on the stress/strain response of individual grains in these engineering alloys. To rectify this situation, fatigue crack initiation and propagation response in a large grained aligned alpha microstructure was studied and supported by an evaluation of the crystallographic orientation adjacent to the crack path. Fatigue crack initiation is shown to be highly dependent on the crystallographic orientation of the colony in which it occurs. Extended fatigue lives occur where basal planes of the initiating colony lie parallel to the applied load. Conversely, basal inclinations of 45° produce short fatigue lives. Stage II fatigue cracks propagate preferentially through colonies with common basal planes. Colony/grain boundaries and alpha lath direction affect crack propagation kinetics. Life to failure is inversely dependent upon applied stress range in all geometries studied. This relationship applies irrespective of whether the alloy cyclically softens or hardens.

Resumen
Small crack growth rates are assessed for the near alpha titanium alloy, IMI 829, with beta processed microstructures. Constant load amplitude tests were conducted using three test piece geometries which encompassed plain surfaces and stress concentrations. Two computerised crack length measurement techniques were used: A switched d.c. potential drop method and a photomicroscopic system. The p.d. system together with a clip gauge were used to assess crack closure. Crack growth is structure sensitive, characterised by crack path tortuosity, crack bifurcation and a faceted fracture surface. Colony and prior beta grain boundaries provide barriers to propagation which result in temporary arrest in many instances. Small crack growth rates were compared and contrasted with available long crack data for the same alloy and microstructure. A transition, ΔKT, was observed for the small crack growth rate data. This transition is most marked for through thickness cracks at notches and least marked for part through cracks in plain surfaces. Small crack growth behaviour was observed for values of ΔK less than ΔK_T with growth rates up to a factor of 10 greater than long crack rates. For values of ΔK greater than ΔKT the data merge, although in some instances rates for through thickness small cracks were slower. The transition from small to long crack behaviour occurs as the monotonic crack tip plastic zone approaches the widmanstatten alpha colony size. At low ΔK there was no evidence of a threshold even at 3.6 MNm^-3/2. Load ratio was not observed to affect growth rates. The results suggest that the significant difference between crack voltage signals during a load cycle, for ΔK above and below ΔKT, could be due to crack tip plasticity rather than closure in this study. Crack closure was not evident from crack opening displacements obtained using the clip gauge.

Resumen
The flow and beta recrystallization behaviour during thermomechanical processing of near-alpha titanium alloy IMI834 (Ti-5.8Al-4Sn-4Zr-1Nb-0.5Mo-0.35Si), with an initial bimodal alpha+beta microstructure, has been investigated. The effects of temperature and strain rate were characterized and modelled at beta and alpha+beta hot working temperatures near the beta to alpha+beta transition temperature (beta transus) to study the quantitative differences in one- and two-phase isothermal forging. The experimental work for characterization and modelling was based on compression testing of lab-scale specimens at temperatures of 975-1100°C, strain rates of 0.01-1s-1, and post-deformation annealing times of 5-420s. Supplementary interrupted compression testing was also performed at 975-1000°C to evaluate the applicability of fractional softening in the determination of static recrystallization kinetics. The stress-strain analysis, which employed corrections for friction and deformation heating, showed increasing stress at increasing strain rates and decreasing temperatures. The stress-temperature dependence increased below the beta transus due to the increasing alpha phase fraction with decreasing temperature. Microstructural observation through optical microscopy indicated dynamic recrystallization occurred, although complete grain refinement and homogeneity was only achieved following static recrystallization. Quantitative measurement via image analysis revealed static recrystallization kinetics increased with temperature for single phase beta pre-deformation microstructures (1060-1100°C). However, bimodal alpha+beta microstructures (1000-1025°C) displayed greater recrystallization rates with decreasing temperature. This behaviour was attributed to the associated increase in alpha phase fraction, which yielded a refinement in initial beta grain size and an increase in favourable nucleation sites. Interrupte
L'évolution de la contrainte d'écoulement et de la recristallisation de la phase beta (beta) de l'alliage de titane IMI834 (Ti-5.8Al-4Sn-4Zr-1Nb-0.5Mo-0.35Si), qui présente une microstructure bimodale, a été étudiée lors d'essais thermomécaniques. Des essais de compression ont été effectués à des températures comprises entre 975°C et 1100°C et à des vitesses de déformation allant de 0,01 à 1s-1. Les échantillons ont ensuite été maintenus à la température de déformation pendant 5 à 420 secondes. Ces essais ont permis de mieux comprendre l'influence de la température et de la vitesse de déformation sur le procédé de forgeage isothermique. Des essais de compression interrompus ont également été effectués pour évaluer l'effet de l'adoucissement sur la cinétique de la recristallisation statique. Un modèle mathématique a ainsi pu être déterminé pour permettre une meilleure compréhension du procédé de forgeage à des températures supérieures et inférieures à la température de transformation allotropique (beta transus). Les courbes de déformation, auxquelles un facteur de correction attribuable à la friction et à la transformation de l'énergie de déformation en chaleur a été appliqué, démontrent que la contrainte est proportionnelle au taux de déformation et inversement proportionnelle à la température de déformation. Lorsque la déformation s'opère à une température inférieure au beta transus, la relation contrainte-température devient plus importante. Dans ces conditions, la microscopie optique révèle la présence de grains recristallisés dynamiquement, bien qu'une microstructure complètement recristallisée ne puisse être atteinte que sous l'influence de la recristallisation statique. L'étude quantitative de la microstructure déformée au-dessus du beta transus, via un système d'analyse d'image, révèle que le taux de recristallisation

Resumen
The effect of fatigue crack closure in IMI 829 has been addressed for cracks growing from plain surfaces and under the influence of a stress concentration. Several test-piece configurations were employed, incuding thick and thin section double edge notches and standard corner crack (CC) geometries. All types incorporated an ultra fine corner slit to bias the crack initiation site. A thin double edge notch (DEN) specimen with a through section starter slit was also tested. Crack closure loads were measured using direct current potential drop (PD) and replica techniques. The primary closure mechanism was found to be a plasticity induced closure. The results indicate the dominance of surface effects. They also permit near tip and wake related closure effects to be resolved. At the higher stresses, notch root plasticity in the thick DEN dominates closure. At lower stresses where elastic conditions prevail, the results were comparable to those found in the plain CC specimen. Much work was carried out to characterise closure of part-through and through thickness cracks in the thin section notch. The transition between the two crack types invoked a complex closure response. A secondary closure mechanism was also identified, for all specimen types. This was roughness induced closure. On the basis of the PD measurements, an effective ΔK was derived which improved correlation of data over the range of stress levels and R values tested. At room temperature, crack lengths were measured using the above PD system and an existing photomicroscopic arrangement. A study of crack shape morphology was carried out using optical and SEM techniques. The observed complex stress and crack length dependency of shape development in thick notch specimens at higher stresses, was explained on the basis of enhanced plasticity induced closure in the notch root. Other deviations from expected shape characteristics, could be rationalised in terms of microstructural interactions.

Resumen
Abstract Titanium alloys are expected to be used as heat-resisting structural materials in the airplane and automotive industries. In this study, the creep properties of near-α Ti alloys consisting of a lamellar microstructure were studied. Ti–8.5wt%Al–8.0wt%Zr–2wt%Mo–1wt%Nb–0.15wt%Si alloy (alloy code, TKT34) and an alloy with 0.1 wt% of added boron (alloy code, TKT35) were used in this study. An ingot was hot forged at a temperature of 1,403 K and hot rolled (caliberrolling) at a temperature of 1,273 K to a reduction rate of approximately 90%. It then underwent solution treatment in a β single-phase region followed by air cooling. Finally, it was subjected to aging treatment for 28.3 ks at a temperature of 863 K and then air-cooled. Two solution treatment conditions were applied: a time of 1.8 ks at a temperature of 1,323 K (high temperature/short time (HS)) and a time of 3.6 ks at a temperature of 1,223 K (low temperature/long time (LL)). The average grain size of the prior β grains showed a tendency of the solution treatment temperature being low and the boron-added alloys tending to be small. The length and thickness of the lamellar of these alloys shortened or thinned owing to the addition of boron and at a low solution treatment temperature. The creep tests were carried out at an applied stress of 137 MPa and a temperature of 923 K in air. The creep rupture life of these alloys was excellent, in order of TKT35 (LL) < TKT34 (LL) < TKT35 (HS) ≦ TKT34 (HS). Therefore, the creep rupture life of these alloys was shown to be superior under the HS solution treatment condition as compared to the LL solution treatment condition. However, the minimum or steady-state strain rate of these alloys became slower in order of TKT 35 (LL)> TKT34 (LL)> TKT34 (HS) ≧ TKT35 (HS). The creep properties depended on the microstructure of the alloys.
