Deformation induced structural effects in cerium

Cold worked substructure and nature of faulting in γ-cerium has been studied using X-ray diffraction methods. The results show anisotropic line broadening and peak asymmetry but only minor peak shifts in cold worked filings. The results can be explained in terms of roughly equal concentrations of extrinsic and intrinsic faults and negligible twin faulting. This interpretation is in accord with the expected relative energies of these faults and kinetics of their formation
