The incommensurate charge-density-wave state, which develops in alpha-uranium below 47 K, was studied in high-resolution X-ray and neutron-scattering experiments. Lock-in transitions of the incommensurate modulation wave vector were observed at 38 K and 22 K and explained in terms of a Landau theory. The simultaneous lock-in transformation of both the q(v) and q(z) components was accompanied by the formation of a phase-discommensuration lattice along the z axis.
