Microstructure and Mechanical Properties of In718 Alloy Produced with Twin-Scanning Atomizer


Article Preview

Sound billets were produced at BIAM with a twin-scanning spray forming facility. Microstructure and mechanical properties of In718 alloy produced with this technology were examined. Both tensile strength and stress rupture properties are excellent with the rupture life even doubled after received a direct aging heat treatment.
