Abstract Scope |
There is significant industrial demand for low-cost polycrystalline Ni-base superalloys that can be utilised for rotating and static applications at intermediate temperatures in aircraft engines. In this work, we report on the microstructure, heat treatment response, mechanical properties and oxidation behaviour of a newly developed alloy for these applications.
The alloy has been designed to improve on the thermal stability and mechanical performance of Inconel718 (IN718), whilst offering lower processing costs than advanced cast & wrought alloys such as Alloy 720Li and Renč 65. The study highlights key areas of alloy development, comparing the alloy properties where possible to current commercially available alternatives. |
