Abstract
A multi-material component joined by a high entropy alloy is provided, as well as methods
Claims20
A multi-material component comprising:
- a first member comprising steel, aluminum, a combination thereof, or an alloy thereof;
- a second member comprising aluminum or an alloy thereof;
- and
- a third member joining the first member to the second member,
- wherein the third member comprises a high entropy alloy comprising at least three principal elements,
- wherein the at least three principal elements comprise Cu, Mn, and Ni, and wherein at least one of the at least three principal elements is present in the high entropy alloy at more than 35 atomic %.
3 more elements
A multi-material component comprising:
- a first member comprising steel, aluminum, a combination thereof, or an alloy thereof;
- a second member comprising aluminum or an alloy thereof;
- and
- a third member joining the first member to the second member,
- wherein the third member comprises a high entropy alloy comprising six principal elements,
- wherein the six principal elements comprise at least four principal major elements and at least one principal minor element,
- wherein the six principal elements are Al, Cu, Fe, Mn, Ni, and Cr.
4 more elements
A method of making a multi-material component comprising:
- providing a first member comprising a first metal or first metal alloy;
- providing a second member comprising a second metal or second metal alloy, wherein the first metal is different from the second metal;
- joining the first member and the second member via a third member comprising a high entropy alloy,
- wherein the high entropy alloy is Cu—Mn—Ni, Al—Fe—Cu—Mn—Ni, or Al—Fe—Cu—Mn—Ni—Cr.
