Abstract

Superalloys are the most diffused material for aeronautical and aerospace applications, mainly for turbines and compressors production, because of their excellent resistance at high temperature. Among them, polycrystalline superalloys Udimet 720Li and Inconel 718Plus are interesting candidates for turbine disc application, due to their high temperature strength, good corrosion resistance and excellent workability. The aim of the present work is to study the low cycle fatigue (LCF) behaviour of these two nickel-base superalloys for aeronautical applications. The experimental tests plan has been predisposed with two different working temperatures (650 and 700°C). Materials were provided from Avio s.p.a. Torino in the form of manufactured article. This project includes tensile and creep tests, too.
