摘要：

Ingots of alumina oxide dispersion strengthened copper (ODSC) were produced through a internal oxidation technique. The ingot was hot-extruded into sticks, which were thus drawn at room temperature into rods with different diameters. It is found that the metallographic structure of the rods has typically fibrous characteristic. With the deformation ratio increasing, the microstructure becomes finer and finer, and consequently, the tensile strength and the hardness could increase while the elongation to fracture and electric conductivity decrease slightly. In the case, reducing the total amount of rod deformation can effectively avoid material sharp hardening, and thus avoid rod hollowness, cracking and other defects.
