Abstract. Mechanical alloying of Cu+3wt.% A1 2 O 3 powder mixture and milling of pure and prealloyed copper powder with 3.5wt.%Al (CuA13.5) have been performed in planetary ball mill in air up to 2oh. All powders have been then treated in H 2 at 400 °C for lh, in order to eliminate formed oxides. Hot pressing was used for compaction (800 °C, 3h, Ar, 35 MPa).
