Two types of alumina dispersion-strengthened Cu alloy were fabricated by surface oxidation reaction by the aging of Cu-0.31 wt%Al and Cu-0.28 wt%Al-0.07 wt%Ti alloys in air. After heat treatment at 980 degrees C for 1 h in air, a 0.2 mm-thick alumina-dispersed plate could be prepared. The alumina-dispersed alloy with Ti addition showed higher values of conductivity, hardness, and tensile strength than the alloy without Ti. (C) 2014 Elsevier B.V. All rights reserved.
