| Abstract Scope |
CP1 is a high-performance Al–Fe–Zr alloy developed by Constellium Aheadd, specifically for laser powder bed fusion (LPBF) systems. The alloy is designed for demanding aerospace applications due to its high thermal conductivity and elevated strength. In this study, CP1 specimens were fabricated using an LPBF Velo3D system and stress relieved following the manufacturer’s recommendation (4h at 400 °C). The builds were machined into tensile and ultrasonic fatigue (USF), where fatigue specimen geometry was defined using Shimadzu USF software based on material properties. Fractography was conducted using a JEOL JSM-IT500 SEM, and Vickers microhardness (HV) was measured using a Qness 30 CHD Master+ system. This work investigates the validity of USF as an accelerated alternative for fatigue characterization. |
