Abstract 718Plus alloy, with its excellent mechanical properties, high temperature resistance, good processability and appropriate manufacturing cost, effectively fills the long-standing alloy blank between alloy IN718 and Waspaloy, and has been gradually applied to manufacturing high performance engine parts. In this paper, the performance characteristics of alloy 718Plus are described in detail, including its chemical composition, precipitation phase, heat treatment and mechanical properties. In addition, the manufacturing cost and its aerospace application are also summarized.
