Abstract

X-ray line broadening characterizations of the stored energy of cold work in axisymmetric OFHC copper rods has been studied as a function of crystallographic orientation and uniaxial strain level. The results were correlated with a path-averaged Taylor factor. As previously reported for plane-strain rolling, the stored energy of cold work is found to increase monotonically with increasing Taylor factor. This correlation is observed to hold over the entire range of strains studied, 0.092 ≤ ε≤ 0.367. Particle size separation of the Fourier line broadening coefficients indicates that particle size effects are dominant in OFHC copper at a strain level of 0.367.
