Heat Treatable Superalloy Developed for Superplastic Forming of High Strength and Hot Gas Corrosion Resistant Parts

摘要

INCONEL alloy 718SPF can be produced with an ASTM grain size of #10 or smaller and subsequently, superplastical-ly formed at 954 deg C (175 deg F) using argon gas pressures of 2.1 MPa (300 psi). The material can be age hardened to high strength (see Fig 3).
