Abstract Scope |
Superalloys have long been desirable for critical aerospace applications, due to their balanced suite of properties. As operating temperatures have continued to rise, coatings for superalloys have played and increasingly important role. Emerging metallic systems showing promise beyond superalloys include cobalt-base alloys, refractory-based materials, multi-principal element alloys, intermetallics and combinations of these classes of materials. Advances in each class are limited by the large potential design space and the complexity of the processing paths. Design tools and approaches that address these challenges are emerging and will be discussed along with future needs in these areas. Current property challenges for each class of material will be highlighted. Finally, the benefits of additive manufacturing as an enabling path for new, higher temperature materials will be addressed. |
