摘要

采用无坩埚感应熔炼超声气体雾化法（Electrode induction melting gas atomization

EIGA）制备了 Inconel 718 预合金粉末，并对预合金粉末进行了表征。通过预合金粉末热等静压工艺制备了 Inconel 718 粉末合金坯料并测试力学性能，力学性能接近锻件。采用有限元法进行了 Inconel 718 环件的热等静压数值模拟，并结合模具设计，实现了粉末高温合金复杂结构件的整体近净成形。

Abstract

Pre-alloyed Inconel 718 powder was prepared by electrode induction melting gas atomization (EIGA) and then characterized. Powder metallurgy (PM) Inconel 718 alloys was prepared through a typical hot isostatic pressing (HIPing) route and its mechanical properties were tested. The mechanical properties were close to that of forgings. The numerical simulation of hot isostatic pressing of Inconel 718 ring was carried out by using the finite element method. Combined with the capsule design

the whole near net shape of PM Inconel 718 complex structure parts was realized.
