Abstract
A multi-material structure includes a refractory portion with a metal or metal alloy of at least one of niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhenium (Re), iridium (Ir), vanadium (V), and ruthenium (Ru). A structural portion is metallurgically joined with the refractory portion. The structural portion includes a titanium (Ti) alloy. At least one of the refractory and structural portions is additively manufactured.
Claims20
A multi-material structure comprising:
- a machined refractory portion provided in a finished configuration, the refractory portion comprising at least one of niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhenium (Re), iridium (Ir), vanadium (V), and ruthenium (Ru);
- an additively manufactured structural portion comprising a titanium alloy, wherein the additively manufactured structural portion further comprises a core having an open cell structure;
- and
- an interface portion metallurgically joining the machined refractory portion and the additively manufactured structural portion.
A multi-material structure comprising:
- a machined refractory portion provided in a finished configuration;
- an additively manufactured structural portion having a physical characteristic different from a physical characteristic of the refractory portion, wherein the additively manufactured structural portion comprises a core having an open cell structure;
- and
- an interface portion metallurgically joining the machined refractory portion and the additively manufactured structural portion.
A multi-material structure comprising:
- a machined refractory portion provided in a finished configuration, the machined refractory portion comprising a body centered cubic metal alloy comprising at least one of niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhenium (Re), iridium (Ir), vanadium (V), and ruthenium (Ru);
- an additively manufactured structural portion comprising a titanium alloy in a phase of at least one of a near-alpha, alpha-beta, near-beta, beta, and gamma, wherein the additively manufactured structural portion comprises at least one of Ti-6Al-4V, Ti-6Al-2Sn-4Zr-2Mo, and TiAl, wherein the additively manufactured structural portion comprises a core having an open cell structure;
- and
- an interface portion metallurgically joining the machined refractory portion and the additively manufactured structural portion.
