Abstract
A multi-material component joined by a high entropy alloy is provided, as well as methods of making a multi-material component by joining dissimilar materials with high entropy alloys.
Claims6
A multi-material component comprising:
- a first member comprising steel, aluminum or an alloy thereof, or a combination thereof,
- a second member comprising aluminum or an alloy thereof, and
- a third member joining the first member to the second member via at least welding,
- wherein the third member comprises a high entropy alloy, wherein the high entropy alloy consists of Al at about 2 atomic %, Cu at about 12 atomic %, Fe at about 22 atomic %, Mn at about 26 atomic %, Ni at about 33 atomic %, and Cr at about 5 atomic %.

A method of making a multi-material component comprising:
- providing a first member comprising steel, aluminum or an alloy thereof, or a combination thereof;
- providing a second member comprising aluminum or an alloy thereof;
- welding together the first member and the second member with a third member therebetween,
- wherein the third member comprises a high entropy alloy, and
- wherein the high entropy alloy consists of Al at about 2 atomic %, Cu at about 12 atomic %, Fe at about 22 atomic %, Mn at about 26 atomic %, Ni at about 33 atomic %, and Cr at about 5 atomic %.
