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 refractory portion comprising at least one of niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhenium (Re), iridium (Ir), vanadium (V), and ruthenium (Ru);
- and
- a structural portion metallurgically joined with the refractory portion, the structural portion comprising a titanium (Ti) alloy,
- wherein at least one of the refractory portion and the structural portion is additively manufactured.
A multi-material structure comprising:
- a refractory portion;
- and
- a structural portion deposited onto the refractory portion, the structural portion having a physical characteristic different from a physical characteristic of the refractory portion,
- wherein the structural portion is deposited onto the refractory portion by additive manufacturing.
A method for manufacturing a multi-material structure comprising a refractory portion and a structural portion metallurgically joined with the refractory portion, 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), the method comprising:
- depositing by additive manufacturing a titanium alloy onto the refractory portion to yield the structural portion.
A method for manufacturing a multi-material structure comprising a refractory portion and a structural portion metallurgically joined with the refractory portion, the structural portion comprising a titanium alloy, the method comprising:
- depositing by additive manufacturing a metal or metal alloy comprising at least one of niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhenium (Re), iridium (Ir), vanadium (V), and ruthenium (Ru) onto the titanium alloy of the structural portion to yield the refractory portion.
