Fabrication of alumina dispersion strengthened copper strips by internal oxidation and hot rolling

Cu–Al alloy strips were internally oxidized without using any oxidant powders by a surface oxidation method. Several of the internally oxidised alloy strips were stacked and bonded by rolling at high temperatures. The bonded strip was cold rolled to achieve tensile strengths of 480–540 MPa and yield strengths of 470–520 MPa with thermally stable mechanical properties.
