MA法により作製したアルミナ分散強化銅の特性 Aluminume Oxide Dispersion Strengthened Copper Produced by Mechanical Alloying Method
Aluminum oxide dispersion strengthened copper (ODSC) wire, in which fine Al<SUB>2</SUB>O<SUB>3</SUB> dispersed uniformly, was manufactured by mechanical alloying, plasma activated sintering, hot extrusion and cold drawing technologies. The relationships between milling time and wire's mechanical and electrical properties were investigated from a viewpoint of the wire's internal structure by using optical microscope, scanning electron microscope and electron plobe microscope analyzer. Obtained results were as follows, (1) 6h milling time was enough for finishing internal oxidation of Cu-0.35mass%Al alloy. (2) Higher than 590N/mm2 tensile strength, higher than 8% fructure elongation and higher than 85%IACS of electric conductivity were obtained by internal oxidized Cu-0.35mass%Al alloy wire of the present study.
