Abstract

In this work, mechanical and electrical properties of copper base composites alloy sstrengthened by dispersed TiB₂ particles are characterized. Powders of copper and TiB₂ were mechanically ball milled in a planetary mill during 12 and 36 h under a protective atmosphere of argon. Resulting powders were compacted uniaxially at 923 K under 90 MPaduring 2 h. Part of these compacts were hot rolled at temperatures ranging between 1073 and 1023 K with 20 % reduction. Comparing the properties of materials after this thermomechanical process with that of as-consolidated, it was observed an electrical conductivity increase, and a decrease on hardness and ductility.
