Silicon wafers have been implanted with boron (3 × 10 14 or 1 × 10 15 ions cm −2 ) and with argon (up to 1 × 10 15 ions cm −2 ). The energies were chosen to approximately superimpose the two impurity distributions. After the boron and argon im

The effect of the state of aggregation of lead on the hardening behaviour of NaCl : Pb and KCl : Pb has been systematically investigated. It is concluded that for KCl : Pb, the yield stress is independent of lead aggregation at concentrations up to a
