| Abstract Scope |
“Old-fashioned” cast & wrought Ni-base superalloys continue to command a significant portion of the materials used in the hot sections of aero- and industrial gas turbines. Considering that legacy alloys like alloy 718 and Waspaloy have been produced commercially for decades, one might be tempted to assume that the physical and process metallurgy of these and other cast & wrought alloys has left nothing to be discovered and controlled. In this author’s opinion, this is not so. As illustrated by ten challenges, covering a wide range from melting and solidification to environmental effects on mechanical properties, some areas with need for ongoing research and continuous improvement are identified. Similar challenges are likely to be encountered in the development and insertion of any new alloys. |
