Microstructure and microhardness of OFHC copper

An ultra high purity oxygen free high conductivity OFHC Cu was investigated to determine the evolution of microstructure and microhardness during processing by high pressure torsion HPT. Disks were processed at ambient temperature, the microstructures were observed at the center, mid radius and near edge positions and the Vickers microhardness was recorded along radial directions.
