Dans le procédé d’hydroformage, la pression d’un fluide est utilisée pour déformer plastiquement un tube paroi mince à l’intérieur d’une matrice fermée afin de remplir la cavité de la matrice. L’hydroformage des tubes possède de nombreux avantages qui rendent ce procédé très intéressant pour plusieurs industries telles que l’automobile et l’aérospatiale. Mais, à cause de différents facteurs tels que la formabilité des matériaux, l’ordre et les séquences du chargement (force de compression axiale et pression interne pendant le procédé), la géométrie de l’outil et la friction, c’est un procédé d

Abstract:

As current aerospace materials are subjected in service to increasingly onerous conditions of stress and temperature, the hazard of fatigue failure becomes more acute. Engineers utilise the methodology of fracture mechanics to estimate fatigue crack growth rates but fatigue crack initiation, which involves the interplay of many microprocesses, is only investigated empirically. The aim of this study was to investigate the fatigue damage accumulation mechanisms in the titanium alloy IMI 834 in order to develop a fundamental understanding of the controlling physical processes and the micromechani

Abstract:

The main purpose of this thesis is to investigate the ductility and application of titanium alloys, like titanium 6Al-4V, when used in aerospace fasteners compared to more conventional stainless steel aerospace fasteners such as A286. There have been concerns raised about the safe usability of titanium 6-4 in the aerospace industry due to its lack of strain hardening. However, there is a lack of data pertaining to this concern of safe usage which this thesis aims to address. Tensile tests were conducted to find the ductility indexes of these fasteners which quantify the amount of plastic to el

Abstract:

The effect of friction stir welding (FSW) on the toughness properties of two aerospace aluminium alloys has been investigated. Two typical aerospace alloys, high strength AA7449 and medium strength AA6013 have been studied in detail. The mechanical properties have been characterised via hardness testing, toughness testing and tensile testing incorporating strain analysis via digital image correlation. A notched 5ar test has been used to produce a profile of toughness across each of the welds and, in AA7449, through the depth of the welded plate. Each fracture surface was examined via FEGSEM to

Aluminium alloys are essential to a variety of industry sectors, particularly transport, where they are used in the production of cars and aeroplanes. However, aluminium alloys are susceptible to degradation through corrosion which can compromise the integrity of components manufactured from this material. Therefore research into the means by which these alloys degrade is important. This thesis aims to understand how one of the more potentially damaging types of corrosion, known as pitting corrosion, occurs in the important aluminium alloy 2024-T3 (AA2024-T3).

Aluminum alloys have been used for decades in aircraft as they offer a wide range of properties explicitly developed to provide a set of characteristics adapted to structural and non-structural components. However, aircraft components inevitably undergo degradation during service due to their extensive use and exposure to harsh environments. Typical repair methods are either not efficient for large scale repairs due to their low material growth rate, not suitable for field repair or involve the use of high process temperatures.

Elevated temperature exposure and mechanical tests up to 427<SUP>o</SUP>C (800<SUP>o</SUP>F) were performed. Constant load creep-rupture tests were also performed. High temperature 8009 Al was found to have outstanding thermal stability up to 427<SUP>o</SUP>C (800<SUP>o</SUP>F). It retained 100% of its tensile properties after exposure for 1000 hours, and afte

Additive Manufacturing (AM) is an innovative manufacturing process which offers near-net shape fabrication of complex components, directly from CAD models, without dies or substantial machining, resulting in a reduction in lead-time, waste, and cost. For example, the buy-to-fly ratio for a titanium component machined from forged billet is typically 10-20:1 compared to 5-7:1 when manufactured by AM. However, the production rates for most AM processes are relatively slow and AM is consequently largely of interest to the aerospace, automotive and biomedical industries. In addition, the solidifica

Hold down release mechanisms (HDRMs) are used for tightly attaching segments of bodies together when it is desired to release them rapidly at some point. When transporting sensitive payloads on launch vehicles, the challenge arises of releasing the fastened segments of the spacecraft without risking damage to the costly equipment. Non-explosive HDRMs are favourable from a safety perspective as there is a lower risk of producing potentially destructive shock-waves throughout the structure. One variant of a non-explosive HDRM uses a so called 'split spool initiator'. This initiator can only be

Titanium alloys have outstanding mechanical properties such as high hardness, a good strength-to-weight ratio and high corrosion resistance. However, their low thermal conductivity and high chemical affinity to tool materials severely impairs their machinability with conventional techniques.

It has been found that the springback angle after unloading depends on the amount of blankholding pressure, the material properties, and the tool geometry.
