Characterization and Validation of Material Parameters of Metal Deposited and Welded Ti-6Al-4V
Titanium alloys are frequently used in aerospace applications due to their superior strength to weight ratio. The most widely used titanium alloy is Ti-6Al-4V, it was invented in the 1950’s and has since then, apart from in aerospace components, been used in medical devices and prostheses because of its biocompability and corrosion resistance. In this project, promising manufacturing methods for producing the next generation of turbine outlet manifold in titanium alloy is investigated. The driving force behind the project is to save weight of Vinci, the upper stage engine of Ariane 5, in which the turbine outlet manifold is located. In addition to low weight, reliable functionality is of great importance, particularly when the final application will transport valuable cargo. To ensure that all requirements are fulfilled, knowledge and understanding of materials are needed all the way throughout the manufacturing process.
