1. A method of making a dispersion strengthened Cu—Cr2Nb alloy, the method comprising:
preparing a mixture of powders, the powders including copper (Cu) powder, chromium (Cr) powder, and niobium (Nb) powder, wherein the Cu powder has a mean particle size of 10-50 μm, the Cr powder has a mean particle size of less than 10 82 m; and the Nb powder has a mean particle size of less than 10 μm, wherein the Cr powder and the Nb powder are combined together and milled prior to forming the mixture with the Cu powder;
melting at least a portion of the mixture using a laser; and
cooling a melted portion of the mixture to form the dispersion strengthened Cu—Cr2Nb alloy.
