Dislocation Density of Oxygen Free Copper with Compressive Strain Applied at High Temperature

Dislocation densities of oxygen-free copper (OFC) with compressive strain applied at high temperatures were examined by X-ray line profile analyses with synchrotron radiation. To evaluate the dislocation density, we applied the modified Williamson-Hall and modified Warren-Averbach methods. The dislocation densities of OFC with compressive strain ranging from 0.9 – 3.8 % were on the order of 1.2×1013 – 4.2×1014 m-2.
