Abstract:

Two principal approaches are available to materials’ engineers to improve the overall cost-weight balance of metallic airframe structures: improving alloy performance and optimising materials’ utilisation. Although both approaches have been successful in the past, they are most effective when applied concomitantly. The Aluminium industry has a long record of improving aerospace alloys’ performance. Nevertheless, even in apparently well-explored alloy systems such as the 7xxx family, products with improved damage tolerance-strength balances have recently been developed, thanks to an improved un

Abstract:

Traditionally the Aerospace Industry has, most often, selected heat treatable aluminum alloys for its sheet metal fairings, panels and skins. With the introduction of superplastic forming (SPF) in the late 70’s and early 80’s the initial applications of SPF aluminum utilized the heat treatable superplastic alloys that were available then (ie. 2004 and 7475). When superplastic 5083 alloy sheet became commercially available in the late 1980’s applications were focused on the ‘high end’ automobile and the European rail markets. More recently, the qualification of SP5083 to aerospace standards, co

A corrosive environment such as salt water can severely degrade the fatigue properties of aluminium alloys used in aerospace applications. The corrosion fatigue crack growth rate properties of two conventional alloys, that is Al-Zn-Mg-Cu-Zr alloy (7010-T7651) and Al-Cu-Mg alloy (2024–T351) have been compared with the more recently developed Al-Li-Cu-Mg alloy (8090-T8771). Increased growth rates were observed in salt water compared to air for 7010 and 8090 but not for 2024.

Titanium alloys are used extensively in the aerospace sector due to the good combination of high strength-to-weight ratio and corrosive resistance. Many aerospace components are exposed to extreme service stress states and temperatures, which in some applications could compromise the component’s performance if a single titanium alloy is used. A potential solution to this issue could be the combination of dissimilar titanium alloys in subcomponent regions, achieved through consolidating powders via field assisted sintering technology (FAST-DB) and subsequent hot forging (FAST-forge).

Abstract:

Titanium alloys are widely used in important manufacturing sectors such as the aerospace industry, internal components of motor or biomechanical components, for the development of functional prostheses. The relationship between mechanical properties and weight and its excellent biocompatibility have positioned this material among the most demanded for specific applications. However, it is necessary to consider the low machinability as a disadvantage in the titanium alloys features. This fact is especially due to the low thermal conductivity, producing significant increases in the temperature o

Abstract:

Next generation fuel-efficient jet engines are running hotter presenting a structural challenge for the exhaust systems and structures adjacent to the engines. A conventional and affordable titanium alloy with superior oxidation resistance provides significant weight reductions and associated cost savings by eliminating the need for high density material systems such as nickel-base superalloys for service temperatures in between current titanium and nickel, enabling major technology advancement in high temperature aerospace applications.

Abstract:

Since the development of the Ti54M titanium alloy in 2003, its application within the aerospace sector has gradually increased due to the combination of properties such as improved forgeability and machinability, low flow stress at elevated temperatures, and superplastic characteristics. However, for the successful exploitation of Ti54M a comprehensive understanding of its mechanical characteristics, microstructure stability, and superplastic behaviour is required. The superplastic forming of titanium alloys is characterised by high deformation at slow strain rates and high temperatures which

Abstract:

High strength aluminium alloys are widely used in the civil and military aerospace industry due to their low weight and high mechanical properties, achieved by selected alloying elements and heat treatments. The resulting multiphase alloy system, a solid solution of alloying elements in the aluminium matrix and a variety of second phase material, requires specific anticorrosion measures in order to prevent localized corrosion, which is promoted by microgalvanic coupling between the different metallographic phases. Traditionally, the anticorrosion performances are achieved by chromic acid anodi

Abstract:

The major concern in the aviation industry is the flight safety. Although great effort has been put into the development of material and system reliability, the failure cases of fatal accidents still occur nowadays. Due to the complexity of the aviation system and the interaction among the failure components, it is difficult to do the failure analysis of the related equipment. This study focused on surveying the failure cases in aviation, which were extracted from failure analysis journals, including Engineering Failure Analysis and Case studies in Engineering Failure Analysis, in order to obt

Abstract:

There has recently been renewed interest in magnesium alloys from both the automotive and aerospace industries. Due to the low density (approximately 35% lower than aluminium) and high specific strength, these alloys can introduce significant weight savings, and consequently fuel savings, to both vehicles and aircraft. Elektron™ 675 is a new alloy based on the magnesium-yttrium-gadolinium ternary system, developed by Magnesium Elektron Ltd. for wrought applications.
