Measurements of the beta-decay half-lives of neutron-rich nuclei (Mg-Ar) in the vicinity of the N = 28 shell closure are reported. Some 22 half-lives have been determined, 12 of which for the first time. Particular emphasis is placed on the results for the Si isotopes, the half-lives of which have been extended from N = 25 to 28. Comparison with QRPA calculations suggests that Si-42 is strongly deformed. This is discussed in the light of a possible weakening of the spin-orbit potential
