    Description

    Ti6Al4V the most widely used Alpha-Beta Ti-alloy for application in medicine, automotive and aerospace, known for its high strength and corrosion resistance, but also its high maximal operating temperature of around 420°C. Combined with its decent weldability under shield atmosphere it became a standard alloy for additive manufacturing processes, especially laser and electron beam based powder bed fusion. While being well studied at room temperature, influence of L-PBF process on its properties at elevated temperatures are little. Therefore, in scope of this work, tensile properties of Ti6Al4V for temperatures from RT up to 450°C for different heat treatments and microstructures as well as powder conditions are investigated and compared to aerospace standards.
