Additive Manufacturing of High Temperature Metals for Hypersonics Applications Project Call
Additive manufacturing (AM) is a proven valuable enabler for the rapid manufacture of complex assemblies. USD(R&E) in collaboration with the Assistant Director, Hypersonics has identified development of AM for high temperature metals as key to timely fielding of hypersonic capabilities and addressing shortfalls of traditional manufacturing processes which are often costly, low-yield, and labor intensive.
Technical Topic Areas
This project call will focus on the following technical topic areas:
Topic Area 1: Reliable manufacturing of complex scramjet flowpath
Among the most critical areas where robust AM is needed is scramjet flow paths for air-breathing hypersonic vehicles. Current state-of-the-art scramjet designs incorporate multiple AM parts produced via multiple builds. These parts are large and incorporate thin walls and complex internal features (cooling channels). Such complexity introduces risks when joining parts and requires a high degree of precision to maintain proper alignment. Approaches are needed to reduce risk via improved AM part joining techniques with reduced thermal input and higher yield.
Topic Area 2: Gradient printing of material systems relevant to hypersonics applications
Assembly of components of dissimilar materials presents another joining challenge, as traditional manufacturing methods may increase corrosion susceptibility and contribute to undesirable stress, degradation, and optical path changes during flight. These risks are particularly relevant for hypersonic glide body substructures which could readily benefit from AM to reduce the need for dissimilar metal joining.
Dissimilar metal joints often include the use of fasteners, welding, or brazing. These joint designs can be susceptible to encountering debits in structural performance due to various geometric, thermal, and chemical factors. Mitigation methods for these risk factors often include complex, low yield manufacturing processes and over-designed (thicker) joint geometries which can negatively impact system performance, cost, and lead time.
Missile Defense Agency (MDA) Hypersonics Missile Defense Architecture is seeking an approach to these issues utilizing gradient material AM. Gradient printing can, in theory, occur within the same class of alloys or transition between different types of materials, but the methods of deposition as well as performance characterization and repeatability determination require additional exploration. Directed Energy Deposition (DED) as well as Chemical Vapor Infiltration (CVI) are two potential methods that could be explored, but do not encompass the breadth of possibilities.
Topic Area 3: Scale-up capabilities for additively manufactured high temperature alloys, such as oxide dispersion strengthened (ODS) multi-principle element alloys (MPEA)
Further investigations in the area of AM for high temperature metals are also needed to scale manufacturing capabilities to alternative alloys. Currently, a majority of AM focus has been on traditional alloys, as many high temperature metals are difficult to weld and thus create severe challenges for processes such as laser powder bed fusion (L-PBF) AM. Promising routes have been developed to progress AM of alloys which outperform conventional high temperature metals, including high temperature nickel superalloys. However, improved scaling of current capabilities is necessary to lend viability to such alternatives for use in hypersonics applications.
